We use 1 BOM for the entire assembly, but the BOM is broken down into
work centers so the SMT parts are assigned to one work center, the THT
parts are assigned to a second work center, and mechanical/housing parts
to a third work center.

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
