How would you like to have this guy evaluate your reflow profile? It was in response to an auditor who require someone they had monitor temperature in both Fahrenheit and Celcius. What a geek Don't put him on the spot. That is not a good thing to

Hi, This Not so easy as one wuold think. Has the thermal pad of yours vias? How many? What's the via's dia? What is the pcb thickness? If the the pcb has a "ground layer" connected (vias) to the pcb thermal pad, it could sometimes be a little bit tri

Our first pass yield across all our products is above 95% but we include anything that does not meet IPC standards. Probably 75% of our failures are not electrical. AOI is a great tool to get a consistent measure of your process. I dont know how anyo

conductor on the narrowest place ~0.07mm we suggest them to go for a PCB solder pad down to 0.30mm. The Conductor width is: 0.2mm The current problem they are having now is that there will be a problem with 14V to narrow the conductor to the narrowe

I am sorry my friend, but I can't recall that specific error number. But it would help if you explain a little bit more about your problem. Remember that an error code Do Not necessary points to a direct root-cause of a problem. First of all we nee

Hi Paul M, There are no silly questions but silly answers.. and here is maybe a few if I understand you correctly: If you consider place anything less than a 1.27mm (50mil) pitch component down or a chip less than a 1210, hey it maybe don't even work

Wow, a lot of questions here...and you are definitely doing some "tough sledding". To the point. If you have 3 - 22" zones you'll have to calc your belt speed and temperatures to match the solder paste requirements with regard to flux activation an

Gerber in general is not best data set for assembly, alot of processing has to be done, manually or via software tools, all with their nice features, but as you state there is no actual datum XY , pin 1 , rotation references thus has to be 'generated

Hi, We are currently working on a board that has 3x 50-pin THT at 1.27mm pitch each. This is too small for us to be able to consistently do on our selective solder. We are instead considering pin in paste. The connector we are using can be spec'd at

Hi Processman, Where I worked before, as an SMT Department Leader, there were two more departments who ran SMT lines, and we had a task from the CEO to decide to how we measure our performances. The result was like this: - first of all, you will ha
