Guaranteeing quality in a Lead Free environment will put the greatest demands on hand

soldering applications. From a repeatability standpoint, all solder joints should be made with

the same temperature, eg. the tip temperature must remain constant! Hand soldering quality is

completely determined by the skills of the operator and the efficiency of the soldering iron.

Due to the fact, however, that irons generally do not recover lost heat fast enough, operators

use high set temperatures (380 440C). These already high temperatures will need to be

even higher for lead free as the process temperature increases by 40C.

How well the iron recovers or puts back the heat lost at the tip and how long the tip remainson the joint, ultimately determines the actual joint temperature. Slow recovering irons will

lead to inconsistent joint temperatures as seen in figure 1 below.

Soldering Iron Heat Recovery Challenges

Figure 1: Old technology, standard soldering irons where the sensor is located far away from the tip will lead to

inconsistent solder joint quality. The tip looses temperature into the joints but does not recover fast enough

before the next joint is made.

Today, soldering iron manufacturers are developing better performing irons, but they are all

based on the tip being attached to the heating element cartridge which means the tip

temperature will overshoot and the tip price is very high (see figure 2). Such irons force

companies to throw away perfectly good and expensive heating elements only because thesmall copper tip at the end is worn out! The tip consumption for lead free will be even higher,

so it is much more important to be concerned about solder tip price and longevity!

Figure 2: Micro power soldering irons offer performance and ergonomic advantages, but have the two major

drawbacks of tip temperature overshoot and expensive heating cartridge tips.

To meet the lead free hand soldering challenge, ERSA is introducing its newest and patent(s)

pending technology for a state of the art solder station the ERSA i-Con and i-Tool! Today

at ERSA, i stands for intelligent, innovative, intuitive, ingenious, interactive, informative

simply ideal! As process windows become smaller, the soldering task becomes more

difficult. True innovation demands more than just a nice slogan, a catchy word. Todays

soldering stations must be intelligent themselves but intuitive for the user. The interactivity

between operator and station must be greater, and the interactivity between stations must be

greater. Truly ingenious solutions are engineered to optimize process quality and productivity

while at the same time reducing operating costs. These are the elements that make up todays

ideal soldering station, and these are precisely the elements that make up the worlds most

intelligent soldering iron ever designed the ERSA i-Tool (see figure 3).

Figure 3: The intelligent i-Tool has a highly advanced PCB integrated into the handle for a level ofinnovationnever before seen in a solder iron.

As the inventor of the first electric soldering iron for production use in 1921, ERSA is very

proud to introduce one of the smallest, lightest, most powerful and most intelligent soldering

irons in the world specifically developed for lead free. The 150W micro heating element

technology allows for similar performance as compared to soldering irons with expensive

heating cartridge tips, but offers standard low cost, exchangeable tips. The revolutionary

Process Window Alarm notifies operators when the iron tip temperature is outside a specified

process window. Three Power Levels offer maximum power and control (no overshoot) for

all soldering applications. The ERSA i-Con (figure 4) offers One Touch easy to use

operation with large, multifunctional display, automatic tool detection, as well as the optionali-Set tool for automatic downloading of settings to all stations in factory.

The ERSA i-Con will also be available in a dual iron digital station, i-Con2, as well as a low cost, lockable

analog version.

Innovative features of this technology:

1. The 150W micro heating element (patents pending) technology allows for standard, low

costs tips to be removed without replacing the expensive heating element each time (see

figures 5 and 10). This can only be achieved via the innovative, multiple sensor heating

element control technology which is a part of the patent application.

Figure 5: the i-Tool is broken down into all re-usable, long lasting parts. The only consumable item is the low

cost tip.

2. The 150W micro heating element technology allows for rapid heat up: room temp to 350C

in approx. 9 seconds; from standby to 350C in approx. 3 seconds. The new technology offers

one of the fastest heat up and recoveries of all soldering irons that have exchangeable, low

cost tips (see figures 6 and 7).

3. Automatic Standby Motion Sensor: the i-Tool has an Electronic Motion Senor Chip (see

figure 3) that recognizes and monitors when the iron is being used. The iron automatically

goes into a lower standby temperature when the iron is put into its stationary holder or is no

longer moving. Stations that use a micro switch in the holder have problems when the iron isnot placed exactly into the right position. Additionally, this sensor allows for documentation

of when the iron is actually soldering if using the optional Process Control Software.

4. Process Window Alarm: this revolutionary feature (patent pending) documents and alarms

the operator with a visual and acoustic signal if the soldering iron tip gets too hot or too cold.

QC can specify a Process Window in which the iron is allowed to work (see figure 7). In this

manner and for the first time ever in the history of hand soldering, it is possible to guarantee

that every solder joint is made with the proper temperature!

The sensor measures the actual tip temperature very close to the tip extremity. The Process Window Alarm

assists the operators in guaranteeing repeatable quality.

5. i-Tool Calibration: unlike other systems, the microprocessor which stores the temperature

calibration of the iron is actually located in the PCB handle (see figure 3). This now allows

for each individual i-Tool to be calibrated independent of the solder station meaning great

time and cost savings. Only the irons need to be taken for calibration which is much easier

and much faster! Additionally, operators can have and use their own calibrated i-Tool, thus

guaranteeing quality regardless of where a calibrated i-Tool is used in the factory.

6.i-Set Tool: this revolutionary feature (optional item) allows for automatic downloading of

station settings and lockout. For process control reasons, todays high end solder stations offer

a password or lockout function. In this manner, the QC manager can set all proper station

settings and then lock the system out. The operator turns on the station and can only work

with those locked settings. The problem is however, that each station must be individually

programmed and locked. By multiple stations, this is a very time intensive procedure for an

expensive QC manager to be doing! The revolutionary i-Set Tool acts as a type of USB stick

allowing for rapid uploading of settings into the i-Set tool and rapid downloading from the

Tool into multiple stations as seen in figure 8 below. Simply upload the station settings from

an i-Con into the i-Set Tool, which looks similar to the i-Tool and plugs right into the sameconnector. The i-Set Tool is then plugged into any other i-Con station and all set parameters

are automatically downloaded in less than 5 seconds and the station is locked out! It is that

fast and that easy!

7. Power Level Settings: this revolutionary feature allows for the use of three different power

settings which control the 150W heating element depending on the heat required for the

soldering job. With state-of-the-art, sensor controlled heating elements; there is always a

balance between heating power and temperature control or overshoot. In other words, when

the tip touches the joint, heat is lost and the heating element must power up to put heat back.When the tip is removed from the joint, heat energy continues to flow in an instant as if the

mass was still present. This will lead to a tip temperature overshoot that can be as high as 80-

100C! See figure 9 below. For many sensitive components and for Mil Spec and Medical

applications, this is unacceptable as components could be damaged by the overheating!

Conversely, a solder application on a heavy mass TH component on a multilayer board or the

soldering of heat shields or metal parts requires all the power available from the heating

element to transfer the necessary heat.

All other technologies available today must find a balance between power and control in the

form of a compromise between these two extremes, and as such, are not optimized for either.

The heating cartridge tip type irons have a rapid recovery on heavy mass joints (copper pennytest), but can have a very large overshoot which can damage sensitive components! The figure

below graphically depicts tip the overshoot which occurs in most high powered irons, and

which will also occur with the i-Tool at Power Level High.

Maximum Power of 150W flows to tip when

energy is drawn into joint. When tip is removedfrom the mass, the energy still flows.

This leads to a large overshoot which can kill asensitive component!

Figure 9: *When maximum energy is allowed to flow to the tip under heavy thermal stress situations, then the tip

temperature will overshoot significantly!

Note: *The 80W transformer in the station can deliver 150W to the i-Tool heating element

non-stop for approx. 60 minutes before the safety switch turns on in order to protect from the

system overheating. The i-Tool heating element, however, will only draw its maximum 150W

for a maximum of 20 seconds. In this manner, the maximum power is available to the iron byusing an optimal size transformer for safe continual use.

A simple but effective Stress Test can reveal how an iron overshoots by using a cup of

water. Figure 10 below describes the method and shows the results of how the i-Tool out

performs competitive technologies.

A cup of water and a temp

measuring unit (DTM 100)can reveal the actual tipovershoot:

1. Set unit to 350C andconfirm with DTM. Makesure a small ball of solderremains on tip.

2. Place hot tip in cup ofwater for approx. 5seconds in order to causethe iron to heat up at fullpower.

3. Remove tip from waterand place tip on DTMsensor with ball of solderon the cross wires. Readtemp overshoot!

*Power Level Low

Figure 10: The Overshoot Stress test reveals how the i-Tool out performs competitive technologies.

The i-Con Power Level setting feature allows for the use of three different power settings

which control the heating element overshoot. At Power Level High, the system uses 100% of

its 150Watts, delivers maximum heat where required and can overshoot as much as 90C.Rapid soldering on heavy mass applications is easy. Power Level Low holds back the heat

delivery in order that there is absolutely no overshoot possible for the safest hand soldering

applications! (see figure 11 below) Power Level Medium is a balance between the two. Thus,

the operator can choose the right setting for the right job either more power or more control!

8. Lead Free, long life i-Tips: Lead free soldering will require higher working process

temperatures as much as 40C higher. In addition, the higher tin (Sn) content in the solder will

greatly increase the stress to the solder tip, thereby decreasing the life of the tip. In order to

increase the tip life, soldering tip manufacturers must increase the amount of iron (Fe) plating

on the tips. The proven ERSADUR plating process will be replaced by the new ERSADUR

LF process (see figure 12 below) for longer life in a lead free working environment.

Figure 12: details the new ERSADUR LF galvanic plating process which has been re-designed to achieve a

longer tip life when working with lead free alloys.

ERSADUR LF - new galvanic plating process for the new Lead Free series soldering tips:

Improved tip precision: +/- 0.1 mm Improved iron plating: 300 600 microns Improved tip life*: 60,000 to 120,000 joints

*Expected tip life depends on factors such as tip temperature, flux, and mechanical pressure.

The new ERSADUR LF tips should last as much as two times longer than the old

ERSADUR tips.

The increased iron required for longer life, however, reduces the thermal performance and

recovery of the tip. For this reason, it is essential to have a very efficient heating system!

Soldering irons which use a heating element cartridge tip are efficient, but are VERY

EXPENSIVE to use when tip life is short and tip price is high!

ERSAs new i-Tool heating technology guarantees the best heat recovery with inexpensive,

exchangeable tips for lead free. The new ERSADUR LF i-Tips guarantee the best

performance and a much longer tip life when working in a lead free environment! The figure

below shows the seven different tip type shapes and sizes currently available.

Figure 13: details the dimensions of the 7 tip types of the 17 standard i-Tips currently available. All i-Tip series

tips are ERSADUR LF tips, thereby guaranteeing the best life time in a lead free working environment.

The innovative features noted above, differ to existing technologies by offering process

controlled, repeatable results via the Process Window Alarm function, that are traceable forthe first time. Additionally, this new technology differs from competitive technologies in that

it offers adaptable power control for both heavy mass and temperature sensitive components.

This is the first iron in the world that can control the different levels of overshoot, thereby

offering maximum safety and maximum flexibility! The intelligent i-Tool is the first soldering

iron which is calibrated independently from the station, thereby saving calibration costs and

guaranteeing quality anywhere in the factory. Finally, this new technology offers the longest

tip life and the lowest tip costs when compared to the expensive heating element cartridge

tips.

Industry problems addressed or solved by this technology:

1. Problems associated with quality and repeatability: this technology offers the worlds

first Process Window Alarm which notifies operator if they are working outside a specified

process window. Each solder joint can be now made with the proper temperature. Overshoot

is not possible, thereby reducing lifted pads and damaged components! All systems can be

locked out, thereby guaranteeing repeatability. Individually calibrated i-Tools can follow an

operator in order to deliver best results anywhere in the factory.

2. Problems associated with productivity: this technology offers ultra fast heat up and

recovery. Additionally, QC managers can use the i-Set Tool for the fastest station setting and

lockout available on the market less than 5 seconds! Finally, individual i-Tool calibrationwill greatly increase calibration productivity.
