Hi Rick,
Yes, we use a 2 BOM system for all mixed technology boards. The main
reason is so we can have an intermediate kanban for the SMT level only.
This helps us balance the SMT line load more evenly due to run and
changeover time variation, and allows for much smaller through hole
runs. It also comes in handy when you have to scrap boards during the
SMT run without having to manually "return" the through hole parts that
weren't used. I have worked for 4 different OEM's and they all used
this approach for the same reasons.
Cheers,
Larry

Subject: [TN] Separate BOM's for Same Assembly
Hi Folks,
Engineering currently produces two separate BOM's for a single board
assembly, 1 for SMD's and the other for PTH parts which are subsequently
entered into the ERP system by Doc Control. Without going into a lot of
detail I understand the reasons for the separate BOM's are related to
production logistics, routings and cost.
I am told this is typical in the industry for OEM's and would like to
either corroborate or debunk this with your responses. I am trying to
determine if the 2 BOM system is necessitated by ERP limitations or the
result of a misguided approach to process development.
Does anyone use the two BOM approach for a single board assembly?
Thanks!
Regards,
Rick
