Where's the rush?

Electronics Forum | Fri Feb 24 04:08:21 EST 2006 | Rob

I think most of the european PCB assemblers will be ready, however taking it further to retail stocks & waste disposal is another matter. Checking the stats of our parent company (a component distributor) 97% of all components shipped are ROHS compl

MANEX ERP or DBA Manufacturing - any user comments?

Thoughts on having AOI catch components that are supposed to be non populated???

Electronics Forum | Thu Feb 21 11:22:06 EST 2013 | emeto

It is a very interesting thought. However, teach all positions on the PCB might be challenging if you don't have them in the file. I think it is a smart think for OEMs as they would have all the resources to control their files. For CEM I don't see i

I forgot to update this. Customer insisted on reflowing SIM card directly to PCB, as per their previous CEM. It worked. No deformation of the SIM card - assembly works - records data to SIM card. Note that using hot air reflow type (rework station)d
