Hi T, Gluing parts to the back side for wave solder is a widely used process. Running waves pallets is probably the last way I would want to run a wave. There are just so many things that have to be done to assure good quality first time pass, tha

TAL Too Long - dull solder joints, dewetting. TAL Too Short - cold solder, insufficient wetting. You want TAL to be as short as possible (but not lower than 30 seconds), but long enough for every solder joint to be above TAL for at least 30 seconds.

Hi, Are we talking about the pick-up tolerance so for any chip component set it to 0.5mm. It will save a lot of trouble right there. As for body tolerence if it is a zero then it will automatically use a standard value, based on the size of the body

I agree that it would be crazy to think that every part a company manufactured had to be re-engineered to allow for higher temps. Out of the question and I NEVER implied that at all. What I said was that Zarrow told us that it was alright to use lea

Hi All, Recently, we encountered strange defect at our SMT line. We can see solder ball spatter around at one of the component pad. This lead to insufficient solder defect at 1 side of the component. The other side of the component look good(Meet

Michelle, Traditionally, the adhesive side is always run first since most designers put passives (resistors, caps) on the adhesive (solder side) of the board. I worked in an environment where we did the adhesive side first, sometimes the boards "sa

I could help you with the SET features if I saw them. It's been about 4 years so I don't remember them off the top of my head. What you would do (nutshell) is get your non-rotated insertions dead center, then step through to a rotated insertion until

We have two, about 2.5 years old and 1.5 years old. We run all kinds of parts and get about 18K to 20K CPH. The pick accuracy is fantastic so have saved a lot of $$$$ by not having dump buckets full of parts at the end of runs. I could not be happier
