After analyzing the pictures I don't think the solder balls are caused by the solder mask. If the problem would be solder mask related the solder balls would only show up on the solder mask but there are also solder balls on the plastic tabs. To me i

Greg, You guys are right, it was a thermistor. I believe the machine was powered up with the wrong voltage. Here is what gets damaged if the transformer is tapped for 230 and you apply 480: 1. Both CPU modules on the MX100 PLC's blown. 2. Both col

Folks, discovered an issue this morning where solder joints on PCBs that came out of wash system have turned BLUE! Bare pads and test points also contaminated but not as obvious visually. Looks like it could be a chemical reaction between wash

First, it's not a simple as thinking just about your electric meter. * Water heaters need to be DI proof, stainless or ceramic. * The longer that DI water is exposed to air, then closer it becomes like tap water. So, you need to be monitoring DI leve

In thirty years of Electronic service I have never had problems with moisture in boards when hand soldered. I have worked on boards in boxes for defense through industrial control, joy rides etc. Sometimes they some back buried in half an inch of dus

Thank you for your response! I was actually the guy who emailed you a few days back regarding the blank.jpg error message in PCBsynergy. I would really like to try it, but that error is preventing me. I don't know how to initiate communication. If

You should also remove all the pump parts and clean them, checking the bearings and seals. Clean completely the parts that allow the solder to flow back into the pot; ours have a spiral that fills with dross. Treat yourself to new nozzles. Tinning

Proc My field service back ground included Electrovert so I know reflow electrical quite well. I've worked on Heller, Conceptronic and Vitronics over the last few years and really there isn't a huge difference if you can read a schematic. I checked

I don't know your machine but you are looking at the most likely areas. Some machines define a placement pressure, other may define an overtravel to make sure the device is firmly placed on the board. There are usually also timings for when the vacuu

Which process do you have a question about? Is there something more specific you're looking for? Basically you're close on the cycle. And this is a very basic cycle, there are many types of nozzles,machines,methods that will do this slightly differe
