PCB DESIGNING FOR ENGINEERS

With the announcement of government of Indias manufacturing policy expected soon, the stage seems to

be well set for robust growth in the PCB market in near future, opening up a minefield of opportunities for

PCB designers

MONIKA BHATI

For any electronics product, printed circuit board(PCB) forms the basic foundation for

interconnecting and packaging. PCBs are used to

mechanically support and electrically connect

electronic components using conductive pathways,

tracks or signal traces etched from copper sheets

laminated on a non-c onductive substrate (source

Wikipedia). PCBs are also referred to as printed

wiring boards (PWBs), or etched wiring boards,

which have evolved over the years from

uncomplicated single- and double-sided plated-

through-hole (PTH) to become multi-layered PCBs.

The fortunes of the PCB industry depend on the

health of IT, telecom, automobile, electronic

gaming and consumer electronics. Due to the rapid

growth of the electronics industry worldwide, the

global PCB market has witnessed a remarkable

growth over the last two decades.

Whats the market like?

Japan and Asia-Pacific collectively contribute a major share to the global PCB market. Amongst Asian countries, India and

China are central to the growth of the PCB industry, thanks to the rapid expansion of electronic manufacturing bases.

This growth is triggered by the shifting of production activities and facilities of key multinational players in these

countries.

The demand from automotive electronics segment drives a positive outlook for the PCB market over the next few years.

As electronic components account for a fair portion of the overall value of materials consumed in cars production, the

stage seems to be well set for robust growth in the PCB market in near future. Without PCB, we can not expect any

electronic circuit. Since a PCB provides physical support as well as interconnections between different electronic

components, there exist great opportunities as well as very good growth in this field worldwide, says Shavinder Singla,

deputy engineer in PCB Lab at Centre for Development of Advanced Computing (CDAC), Mohali.

K. Krithiga, technical lead at CADD Center, adds, For electricals and electronics engineering (EEE) and electronics

communication engineering (EC) students, this is a good field to start their career. What they have studied during their

engineering course, they should apply to circuit design and PCB design. Initially, engineering graduates can enter into

this field as a circuit designer or a board designer.

A glimpse

PCB designers are key persons in research and development (R&D), electronics production units as well as in the PCB

industry. A PCB designers job comes with a lot of responsibilities. Nowadays its not only about making interconnections

between electronic components but also understanding the functioning of the circuit. It is often observed that a circuit

which functions well when assembled over a bread board may or may not function properly over a poorly designed PCB

layout. Depending upon the complexity of the circuit or PCB it may take two to three days for system engineers to

locate and rectify the problems, Singla says.

There can be numerous reasons for such kind of failures; PCB design and fabrication being one of them. If a PCB is not

designed or fabricated as per the circuit requirements, the circuit may not function at all, or function partially. Generally,

compensate for the delay. Sometimes PCB designers or fabricators are not allowed to devote sufficient time as

intended, Singla explains.

"Without PCB, we can not expect any electronic circuit. Since a PCB provides physica

support as well as interconnections between different electronic components, there exist

great opportunities as well as very good growth in this field worldwide."

Shavinder Singla, deputy engineer in PCB Lab at Centre for Development of Advanced Computing

(CDAC), Mohal

"For electricals and electronics engineering (EEE) and electronics communication

engineering (EC) students, this is a good field to start their career."

K. Krithiga, technical lead, CADD Center

According to Vikas Kohli, senior architect, Cadence Design Systems India, New computing, network, and

telecommunication products have ine-radicably altered the PCB design landscape. A recent report titled Design Trends

and EDA Tool UsageAsia Pacific, highlights consumer electronics, telecom/data communications and industria

control/medical electronics as dominant industries in the region. The PCB design section report shows that over 50 pe

cent of designs have less than 50 integrated circuits (ICs) on a board. In fact, 20 per cent of designs have less than

four ICs on the board. The pin-count of these devices has increased, so has the complexity of the logical interconnects.

In this case, a smaller number of larger components means a larger number of design headaches.

One design disc ipline greatly affec ted by this change is schematic design capture. To keep pac e with shrinking marketwindows in light of all this complexity, designers have to capture designs faster than ever before. And to meet

profitability goals they have to design it right the first time, Kohli adds.

What your pocket says

Lets turn to money matters. This field offers enough provisions for learning as well as earning. The starting salary for a

fresher is typically between Rs 150,000 and Rs 200,000 per annum with impressive year to year hikes. Coming to

experienced professionals, the PCB industry offers salary in the range of Rs 500,000 to Rs 600,000 per annum for people

with four to five years of experience.

As a fresher one can not expect high salary. But after an experience of five-six years, and with understanding and

implementation of standards, one can expect a very good package and may act as a team leader, adds Singla. And of

course if you grab an international opportunity, the pay is quite good even for freshers. It is needless to mention that

PCB designers can experience much better growth while working with an MNC.

Its been my experience that the designers who work on the higher-end or more expensive CAD tools (i.e., Cadence

Allegro and Mentor Graphics) seem to get paid a little higher than designers who work on the lower-end or less expensivesystems like Altium and PADS. As I mentioned earlier, back in the late 90s, as long as you were a good designer you

would be hired regardless of the CAD tool. But now, unfortunately, hiring-managers seem to put an emphasis on which

CAD systems youre running and even what version, etc, opines Derek Doucette, an executive with American Contract

Group, a Massachusetts-based staffing firm. He has been placing candidates into PCB design positions since the 1990s.

A designer once told me, Besides a few features here and there, they basically all do the same thing.

You just need to find out where they place the buttons. I believe that if you

are a good designer on one CAD system, with a slight learning curve, you

should be able to pick up another system with no problem, Derek told

PCBDesign007 in an interview.

Whos hiring?

It is difficult to point out a particular industry as the major recruiter of PCB

designers. Aspirants in this field may look for opportunities in all industries which

are directly involved in manufacturing electronics products. These include

telecom, automotive, biomedical equipment, computer hardware, electronicsecurity systems, consumer electronic appliances, mobile companies, industria

automation and power electronics, amongst others.

The big organisations always have a team of six-eight designers while the

middle ones have two-five designers. The team size depends upon the

development of new hardware or modification of the existing one, and also on

the size of the R&D team. However, to name a few, some of the major

recruiters in this field are Bharat Electronics Limited, Semiconductor Complex

Laboratory, HCL, L&T, GE, HP, Beetel, Nokia, Samsung, LG, Ericsson, Sony and

Philips, informs Singla.

Krithiga adds, Small-sector PCB design companies are recruiting freshers. MNCs like Wipro, Applied Materials, TCS,

Ingersoll Rand, and most of the electronics goods designing companies offer a good opportunity for PCB design

engineers.

Recruiters look for electronic and information engineering (EIE), EEE and ECE engineers with basic electronics

components knowledge with any board design software like OrCAD, Allegro, Altium or PADS. At present, most of the

companies are using Or-CAD and Allegro for c ircuit board design.

A PCB designers must haves as stated by Singla are as follows:

1. Understanding of the funct ioning of an electronic circuit.

2. Knowledge of IPC/Mil standards.

3. Know the process of PCB manufacturing, assembling and test ing.

4. Good knowledge of various electronic components packaging.

5. Know about different PCB base materials.

6. Able to interact with circuit designers, PCB manufacturing and assembling team.

7. Knowledge of EMI/EMC.

If the PCBs are not designed properly, one runs the risk of facing a high level of rework/rejection of populated or

unpopulated PCBs. I have also seen a lot of circuit malfunctions/ failures in the field, which are a result of poor design,

fabrication or soldering techniques, Singla says. He also suggests that PCB designers should have a detailed knowledge

of not only PCB fabrication but also soldering techniques. Also, they are required to be kept abreast of the limitations of

PCB manufacturers with respect to minimum drill-size, minimum track-width, minimum track-to-track and track-to-pad
