In circuit test (possible rework)

From the Screen Printing step to the Optical Test : these

manufacturing steps are carried out in serial (the slowest

equipment causes an additional immobilization of the other

equipment).

Functional Test

Manual Placement of Through Hole Components (TH) and

Connectors.

Wave Soldering and withdrawal of the protective carrier.

Same operations are done on the 2d side.

A Protective Carrier/Pallet is mounted on the panel to protect the

SMD component from the Wave Soldering.

Depaneling

Conditioning

A resin is deposited on both side of the Board
