I have a customer who is transitioning from 100% thru hole boards to designing boards with smt components. We gave them our basic DFM guidelines and they have laid out 2 boards following these guidelines. When I saw the result of their first pass, I

I have a through hole product that is currently built with HMP solder(93.5Pb,5Sn,Ag1.5). We then dip it in 60/40 SnPb to give a solderable finish as HMP tends to oxidise. We need the HMP as our Customers solder through reflow ovens. Some customers w

"Guest" is right, actually. CSP's are essentially BGA's, but typically the pitch and ball diameters are much smaller and in some cases, the pads of the CSP's can not be screen printed. If that's the case, you'd have to have flux-dip capabilities on

I would like some input on reworking BGA's and the best method. I have reworked BGA's since 1998 using both micro stencils and just flux dipping the parts. I have reworked SN/PB and lead-free (AIM NC258) BGA's for the last 8 yrs. with just flux. I ha

Dear Friends, Need your valuable feedback on how to identify the component is ok or not for manufacturing. Issue : We have parts which are more than 5 years old.And management want us to qualify this parts for production. We presently use below me

Due to couple of customers who still have some products that are completely through-hole, we use our Universal DIP and Axial equipment on a somewhat regular basis. Our machines are pretty old, but they work pretty well, and we don't do enough throug

I was a bit amused the way you "tanked" that dip John. I mean you skewered him without benefit of remoulade, that puppy was tarred and feathered, chopped, chromed, toasted!!! I was a bit surprised that you chose to get back into the thread, it didn't

Sounds like you have a component problem! I say this because you say the sodler is flowing away from the components (leads I assume) This sounds like none wetting of the component. Do a solderability test on the parts. Take the parts and dip the lead

| The machine is a Universal 6796 DIP inserter. The driver card for the X axis burned a couple of resistors and a trace, probably a couple of power transistors too. I had a spare card and put it in. Now on powering-up the machine, the X-Y table mo
