ZhongFeng Electronic Technology Co., Limited

PCB Assembly

ZF Electronic is a professional custom PCB assembly manufacturer and we have done turnkey PCB Assembly service from 2003. We own a PCB factory, a PCB assembly workshop (6 SMT lines, 2 DIP lines, 2 AOI, Reflow/Wave soldering ovens, X-Ray tester etc.) and a experienced components sourcing team in Shenzhen China.


Our electronic printed circuit board assembly service could support our customers from prototype PCB assembly to big volume PCB assembly production. As a PCB assembly manufacturer, our aim is to provide highest possible quality electronic board assembly service with affordable price in quick lead time.

Files Required



Files Required


Specification
Gerber files*


Gerber files in format of RS-274X for PCB fabrication


BOM file*


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.

Click to download our BOM Template for reference.


Pick & Place file*


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

(if you have)


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 & Test Fixtures

(if you have)


To ensure the boards quality, we can test the boards following the provided testing guide & test fixtures before shipping.


Programming files & Programming tool

(if necessary)


We could do IC programing for our customers if required.
