| Greetings, | | We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? | What about those components which come on blister tape, should they get baked and r

Check to see if there's a loose cable, or something, that's randomly setting off the light curtain. We occasionally have that problem with some of our flex or 12/16 mags in our TP9, where the tape take up clip is loose (nothing in that feeder) and i

All of our moisture sensitive components are shipped to us in vacuum sealed, desiccated bags with a moisture indicator. When the parts are removed from the bag (this is done at either SMT setup, or in the stockroom) the indicator is checked. If it

Conductive contamination and the elusive solution

Electronics Forum | Thu Jul 12 14:46:13 EDT 2007 | losersk8er

I'm new to the website so if I don't sound like I know what I'm talking about I probably don't. But I am having a great problem at work with conductive contamination that bridges two leads and shorts out the IC, causint costly repair. I have been t

First question I have for you is: Are you assuming that standard precautions are in place at your facility to minimize moisture content i.e. air- deionizers, vacuum sealed packaging, humidity control in storage and manufacturing? You do not mention

ultra low cost pick and place?

Electronics Forum | Sat Jun 12 19:48:47 EDT 2010 | bootstrap

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

Possibility of a cheaper pick and place machine design?

Andres, I think if you were to understand the process a little better you would realise the many many problems you would encounter building even very simple things using your method. Even 30 minutes watching Youtube videos of current machines might h
