Hello Esteemed Panel, I have a question...what is the most cost effective way to get power to a PCB? By this I mean connecting power and ground without a connector but something more reliable than soldering a wire directly to the PCB. Whatever solut

Much ado about nothing. Reminding has failed? Who runs the place? You sound like you are a person in authority. You may not be the boss, but authority has weight. The folks that can't seem to remember (or care to remember) have bosses that you c

Hey Gyver: Oooow, using a pencil eraser has to take time. I would hate to be the person responding to your customer trying to explain the pencil eraser shreds accidentally left on the board. Awww, just spritz it with DI water and wipe it off with

You proved that the standard solderability test of components may be effective for assessing aged components. Curious Minds Can you get the authorization to use a more aggressive flux? Will that flux solve the problem? What's it going to cost to qu

We can offer two ways. We have a process control tool for OSP boards to validate the finish......but the dates yer talking may be best to take Daves F suggestion. NOW as far as the HASL finish goes...We may have your answer. We can Chemically revers

Hello, Mr. Evtimov is right. What kind of pick and place machine do you have? Implementing the MSL into a datamatrix barcode is the first step. Then you might want to use your machine's software solution (if possible) to track this. Another solution

Hi SMT World, I am facing a technical challenge related to an SOIC 14lds with thermal pad on it's belly that needs to be soldered onto PCB, together with leads. It is a 50 per board, expected 80% solder load on every one. We have some units without

Thanks for your reply Sarason. I'm aware now that my goals seem very ambitious and infeasible. Let me formulate my problem in an different way that might be more realistic. Is it possible to measure a DIFFERENCE in strain between top and middle la
