Hi Peter, Out of the 1.5 billion components we shipped last year, we had 3 components back for solderability issues. All 3 had been taken out of their vacuum packaging and left to oxidize for a number of weeks. We don't see it as an issue, but we

Hi everybody. I'm new at SMT soldering. I'm using a stencil to print solder paste on PCB. and my board has 0402 components that it make assembling process long so I can't complete a set of board in a day and I have to continue in the next day. what

Here's a related question: How hot can a PBGA get before popcorn delamination becomes a concern? 100 C? 150C? I realize that the answer will depend upon the conditioning of the part, so let's assume that the part is saturated with moisture. A pra

What's this about a minimum wage for drivel? 1 cent is where it's at! Competetive preassure in the marketplace will improve the quality of drivel for all! That is unless the 'You get what you pay for' law is invoked, then high priced drivel will d

My first posting was not very clear -- sorry. Let me try again. What I want to know is: can I eliminate the drying (baking) process completely IF I know that the good parts (i.e., those not being reworked) are going to stay under some threshold tem

My small R&D company (15 people) is considering the purchase of a bench top reflow oven & associated gear. The reasoning is that it would be nice to have reflow capability for 5 to 50 piece prototype runs in-house. As the only person with any real kn

The assembly process involves activity before you get to reflow. Reflowing is the easy part. Putting paste down and placing parts in wet paste is the terrifying part. Benchtop reflow ovens can be a real handy tool for small production but with the g

Hi I think I agree with this poster. You will be surprised once you get the reflow oven working well how much you will say "And why did I do it the other way" I know, I know "I'm an artist" "I'm an inventor" Nothing wrong with being either yet

Currently we hand-assemble all prototypes, usually quantities less than ten. I mentioned the 5 to 50 number because a client will occasionally request more than ten, which has been handled previously by using an outside contract manufacturer (we are
