I'm looking for advise on setting up a prototype station for smt (we are currently outsourcing smt production, but have a need for rapid in house prototyping). The station must be able to handle only single sided boards with components no smaller th

SMT assembly, First, you must utilize paste otherwise the parts will not stay put. Do you have any leaded devices such as QFPs or SOICs? Dispensing paste by hand is very difficult and time consuming for these types of parts. You can either dispense

We have a problem with dendritic growth that is affecting a new board going into production. This is of concern because they were subjected to Damp Heat Cyclic Tests as part of the product validation testing during their development. Fails to date

Chris, We also do not allow the use of Lead-Free BGAs in a lead based process. It is actually one of the things that scares us most about converting to Pb-free. Most of the suppliers that we have talked with are planning on moving to the SAC

Hi, It's both really, and we are doing higher volume of current products, but new products are increasing in component count, mostly passives. We have analog on our products, and this uses a lot of passives, plus each semiconductor needs decoupling

Rob, I also appreciate the banter. It is good to have these discussions with end users in a (hopefully) non sales environment. Philips actually started building Pick and Place machines in 1980 for high volume accounts. They started out because th

Tom, has your company started to convert your BOMS? How is your company doing it? Yes, I think that is on most peoples minds, how to do the BOM conversions is the main worry, and I think that it just boggs some companies down so they dont do anyt

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

Good Morning TM, We have a table top AOI (actually several of them) We did a side by side evaluation when we first looked at it. We looked at Qualectron, NSpec and Mirtec (Samsung at the time). Some of the criteria that was important to us: *Librar

For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably
