Hi ! The main problem being faced currently is formation of solder balls - to be precise, these are micro solder beads generally found attached with bodies of SOTs, Chip Caps, Chip Resistors, between pins of SOICs (50 mil) - lying on PCB surface,

many solder-ball issues can be resolved by reducing the aperture size, usually 10 to 15% reduction will work. If the aperture size is the same as the pad size paste tends to be squished out under the part, paste off pad under the part will liquify a

Quick question for you Netters out there: Anyone out there dispense solder paste (via automated dispenser) for 0402, 0201 and/or uBGA's? If so, success yields, equipment used, and any technical info would be appreciated. This is for a low volume app

Hi, What's the best process for going lead free? Ordering lead free parts and using them with current paste, and then once all the parts are lead free, moving to lead free paste as well? Then the wave will be fun to change over. What a nightmare th

Hi, Yes, it was quite funny, and everyone thought I was nuts, but it was something worth trying. It's often the weirdest ideas that work. The full tube was ok, but the half full one generated the plasma. That scared the hell out of us when it lit up

I have seen as little gain as 2 months and even up to 6 months additional time to end-of life. Treat solder paste as a perishible item. Note DOM and Refridgeration life and expiration periods. You guys crack me up....now when ever I go to 7-11 I'l

Snehal, Look at the spec sheet for the paper phenoline PCB. Look at the max temp. If it is at or lower than 183 degrees C, here lies the problem. If it will withstand higher temps at a shorter durration, you can possibly speed up the belt but like D

Hi Davef & C Lampron. Thanks for your reply. since i'm using RMA9086 62/36/2 Cookson no clean flux paste.so what do you think if i will switch on to the paste without no clean flux for PP board is there be any chance that i get a +ve result. Awaiting

Hi Mike, Thanks for the comments. We are upgrading our post reflow inspection - primarily solder joint inspection, and capable of keeping up with a maximum of 80K components an hour. Solder paste inspection is currently carried out by our prin
