We are not doing this right at the moment but I have done it with great success. Of cource it depends on your pad layout we have a 20 mil gap in between pads, we printed at 10 mil wide with a 5mil stencil. I will try to find the glue we used, I kno

Russ, We can not use a wave pallet, already went that route. We have parts next to the thru-hole pins and between thru-hole pins. I am going to try an experiment in the next day or so with solder mask. I plan to solder SMT parts on the back of se

Well, I have not had a chance to run my experiment yet. I hope to have the wave solder machine to myself on Friday morning. I will let you know. I am hopefull from what you and the others have said that it will work and we can reduce our touch lab

I doubt you will be able to get satisfactory results with 0201. 0402 is another story. When doing 0402 projects, we use only electric (MP) feeders and always at the same feeder slots (feeder teach done for each of them). MPF08 nozzle works fine. Also

I'm looking for some data to support my argument that HASL boards are not the most ideal boards for manufacturing involving BGA's and 0402's. I'm sure one of you SMT Gurus out there can point me in the right direction! Thank you in advance!

We did 0402s for years on a GSM. Is this a flexjet or a 4 spindle head? A flexjet is easy with 0402s. The four spindle nozzles are big, you run into issues with knocking already places parts and having to Z zone carefully (and beware repair cycles.)

Is anyone successfully and repeatably placing 0402 or 0201 components with an older GSM? We're looking at the possibility of quoting a new job with 0201's, and I need to assess the capabilities of the machine before I commit to the job. I've never

GSMs are great machines for many parts, but for the small parts you should look for something better and more contemporary. As it was mentioned in one of the previous posts, the feeder is a big key. I don't think there is feeder for GSM that can supp
