The Manufacturing process
Once you have board layout files and a parts list we can start manufacturing prototypes or production boards. Let’s make sure we have everything in order first, though:
Board Layout (Gerber) files - made from the schematic. If you don’t have these or a schematic yet, check out our design services page.
Parts list (bill of materials, or BOM) with manufacturer part numbers, quantities of each part and reference designators. Head back to design services page if you don’t have these yet.
From your board layout files we will create and manufacture the “bare” circuit boards. We will also use these files to make a paste stencil for our SMT line. Your board layout files include pick & place data for the SMT line. From your parts list we create a “Datran BOM” that we use along with the pick & place data to program the SMT machines. The Datran BOM is entered into our MRP system for parts ordering and tracking, also.
After programming, the machines quickly and accurately assemble the surface mount components. SMT programs are kept on file for future manufacturing runs and can be easily modified as your product matures. Upon completion of SMT assembly the boards are inspected and any needed through-hole components are added by hand (or by wave soldering machines, depending on board quantity and through-hole parts count).
Let’s take a look at some boards after SMT and through-hole work is done:
