Tony, We have a splicing service that would enable you to take a reel of 1,000 to 5,000 components and splice it down onto reels of 100, 250, 500, etc. parts for use in production. The price is $10 per splice and there is a set-up charge of $100 but

Hey that was me way back! Anyways, use Dow 3140 (self leveling) or Dow 3145 (peanut butter consistency) and call it a day. No out gassing/acidic properties. 3140 also contains a UV tracer for black light inspection. Any tall caps should be epoxied if

Hi everybody, I found a defect varistor 0603 Tombstone and poor welting when we use component that terminal is Silver palladium (Ag/ Pd) with Leaded solder paste (63/37). Then we change alternative component that terminal is Ni/ Sn the result not fou

Get the ionic specs from your flux manufacturer, and show it to the designer. No-clean flux/solder is supposed to be low to minimal in ionic contamination, which allow the whole no-clean thing. If he needs further proof, you can have the board io

We test for board cleanliness using an ionic tester. It's been my experience that if your board is clean you take away the possibility of growth even if the unit encounters moisture. We actaully had a problem where our wash lost pressure due to a mi

Gerber standard has been around for long time as a fabrication data model for PCB makers, but not very useful for assemblers as no centroid data is actually present in the data. Also netlists are no supported and have to be calcualated with software

Senior, below, is correct. THe narrow view camera has to be upgraded in order to place 0201 components. Also to pick the parts you need the 0201 feeders. These feeders present the part 0.3 mm higher than the standard 0402 feeder. The part pickup heig

In that case the same tools can apply, just different implementation. We might use any a number of visual aids for an assembly, one for each component type (resisors, capacitors, ICs, etc.). In the case you're describing we might color code the lo

We had the misfortune of ending up with a batch of Kester EM907 that would start to "set up" well before it's shelf life was over. Since the lead time for a new batch was excessive, a Kester technical guru came to our facility to help us deal with t

I set up some lead-free profiles on a new Heller1700xxx (Compact series), do not know if this is same model you refer to. Can be done, yes speed is a little slower than longer Heller Versions due to zones being so narrow, but doable. Of course all de
