I would love to jump on a program like that, but allocating the resources is hard. I am going to need to put together a proposal on why all of this is going to be useful to people that do not understand. I am having a difficult time just writing up

is there any standard gap between the terminal and pad if we place the glue? SMT-4 mention as per what you understand which is using glue at SMT without solder paste and run at wave solder for the solder paste at the terminal. Glue supplier recomm

Paul, My sincere apologies for striking a nerve - that was not my intent. I do not work for a board house, nor am I pushing anything on you. My comments only come from my history of having to use parts that made manufacturing a nightmare. I do unders

Hello, If I do understand it correct, the dust in your oven are salt-crystals, comming from No-clean fluxes. We had them also once, it was a problem with one fan in the oven, I think you should check your fans inside the oven. Our extraction was OK,

Steve, Trying to keep wave solder from coming up the via' from the bottom and adhering to the via's and via's pads during wave. We use WS flux thru-out the whole process. I have been concerned about possible flux intrapment in the via's. That's a g

Poor reading skills......that being said, with good resolution (3 megapixel and up) digital cameras so readily available, and cheap, why not use real pictures? After all, a picture's worth a thousand words... In the '90s, I used to translate CAD/Ge

From what I understand, the major reason Sn prices recently escalated was a crackdown on black market Sn mining in Indonesia, where most of our Sn originates. Add to that increased demand (not necessarily from RoHS, but from China, India, and other

That you have 'grainy' solder only at the ends of the connector and not at all solder connections indicates that your quality types are on track and are pointing you in a direction worthy of investigation and developing a better understanding of the

Does anyone have an easy way to estimate how much solder paste is applied to a smt pcb? I understand it varies on squeegee pressure, stencil thickness, and pitch of the components but I was looking for an average. I would assume that somewhere out th
