Strict PCBA tests
Below are PCBA Tests we applied:
lVisual Inspection,
lX-Ray Inspection( for BGA and QFN package chips),
lAOI Inspection( for normal SMD package parts),
llCT Test and Functional test ( can guarantee all boards qualified before delivery).
Files Required for making Quotation and Production
Files Required
Gerbe files*(for quote and production)
Gerber files in format of RS-274X for PCB fabrication
BOM file*(for quote and production)
BOM file in excel format for components sourcing and PCB assembly. It should include the components basic information: Reference Designators, Quantity, Part number, Description, etc..
Pick & Place file (for production)
Also known as Centroid file or XY data. It describes the position and orientation of all the surface mount parts and it can help us to quickly programming the SMT assembly machines
Assembly drawing (for production)
It includes the positions and polarities of the components designators which can help us better understand your assembly needs, correcting some ambiguous or even mistaken placements, and ends up with an excellent job
Testing Guide (for functional test)
To ensure the boards quality, we can test the boards following the provided testing guide before shipping.
Programming files (for programming)
We could do IC programming for our customers if required.
Our quick-turn prototyping PCB assembly service can assemble your boards within 24 hours. We can handle small quantity PCB assembly, as well as volume production PCB assembly. All our services are at a very competitive price and with 100% satisfaction guarantee.
