Hi, Can anyone provide a check-list to evaluate the capability of a subcontractor for assembling boards? I mean a list of items to check like number of SMT production lines, kind of machines (screen-printer, pick-and-place, oven, AOI, etc.), throug

Just because someone has great equipment doesn't mean they are any good at assembling quality boards. By all means check out their current capacity & contingency plans, but also assess their competance levels & output quality. Set a cunning trap fo

Verify that the CEMs machines and processes are capable of assembling the technology of your boards- smallest components, largest components, finest pitch, flex circuits, etc� Are their core competences aligned with your requirements- assembly only,

In the fine SMTnet Library, there is a "Terms & Definitions" section that covers CEM-3 and similar items.

Does anyone have experience singulating CEM-1 substrates?

As long as it has been properly stored, we don't believe that old CEM will singulate any different than new CEM ... either should press well.

| We are considering adding surface mount components to a board we currently produce. The board is made from CEM-1. Has anyone had any problems with surface mounting to this material? We use a glue/place/cure process. | | Thanks in advance, | |
