PCB Assembly Process: Standard PCBA Procedure

PCB Assembly standard PCBA procedure

As customers ordered the PCBA(Printed Circuit Board Assembly) service, and payment completed, Makerfabs projects manager will kick off the PCBA manufacturing, and the whole PCBA production process starts as:

 
1. Project Kicking off. 
Makerfabs project manager will start the project via internal ERP system, and also emails, to the engineer dept (ED), to apply the production.
 
2. Internal engineering.
The ED check all the production files if they are proper& enough for production.  If yes, ED notify the production dept (PD) to star the project.  Meanwhile,  ED need to prepare the testing method, sometimes, testing jigs needed.
 
3. Components Souring.
PD notify the purchasing dept to begin the related sourcing& purchasing work. Mainly components& PCB board& stencil, lead time  normally 1~2 weeks.
 
4. Component checking.
Purchasing dept send all the materials to production dept for checking and confirmation.
 
5. Production schedule.
PD PMC(production manager control) begin to arrange the  production line, to schedule the SMD soldering.
 
6. Prototyping.
SMD programming, and reflow oven temperature adjusting.  And make the first 1 pcs prototyping circuit boards.

7. Prototyping checking. 
Engineers in ED check the first sample, especially the components /oritation/. If questions, negotiate with the project manager, or the final customer. If OK, confirm for further production.
 
8. Mass SMD soldering with pick-n-place machine.
 
9. AOI checking for SMD soldering, and repair if any problems.
 
10. THT soldering. 
Boards will be soldered manually, or wave soldering, depends on the quantity, and boards design. if wave soldering, fixture needed.
 
11. Function testing. Engineers in ED will test all the PCBA 100%. And if any boards do not pass, repairing.
 
12. Visual checking, check out bad-looking boards.
 
13. Packaging for shipping.

This is very simple steps for Makerfabs PCB assembly, and actually in project it would be much more complex, and lots of steps to verify all circuit boards are produced as intended to 100% boards testing OK as they are shipped to Makerfabs cooperators. Contact us to get your PCBA Quote Now!
