Hi Lupo, Are you talking about laser trimming the current limiting resistors in front of the LEDs, whilst dynamically measuring their output to get set light levels? If so then you need a laser trimmer & a very good photodiode/comparator feedback l

I need everyone's input. I am in sales and marketing for a PCB shop. I need to know by a vote from any CM's why my CM does not like Immersion White Tin and my other resources have no problems or complaints using white tin. Every time an issue comes u

Solderability!!! The CM in question has probably seen too many solder problems with White Tin in the past. We have had the same issues. To save us from spending too much time and money(verifying pure Tin plating thickness, Chemical leaching from th

It's been years, so take my comments as being worth what you're paying for them. ;) Sounds like it could be running out of memory space. I don't remember anything about being able to clear it or whether or not the exec shares space with anything els

Good calculation, i have to say. Do you forgot, If you let the machine cool down during night, the rest-temperature isn't roomtemperature? right, dont you think the temperature will be something about 140�C ??? heating up time then is not 3 hours. m

Thanks for the feedback. The Finetech machines look very nice, but are far out of our budget. While we are looking for the most cost effective solution, we are able to spend ~$15K on this machine. We really just need a reliable way to remove and rep

Hi, We have a soltec wave, and apart from the really bad software running it, I am wondering if it's time to replace it with selective soldering, which will use less solder, and much less power than a wave. What is a good inline replacement for a w

Hi Jerry, Sounds like the white stuff is flux. I doubt if 4 pcb mfgers could be undercuring all at once. Good point though. Since you changed washers and now have the problem - it's your new washer. Can you bring back the old one to make sure?

Thanks Patrick, also IPC-HDBK-001 explains even better then IPC-J-STD-004, but unfortunately not yet infos about flux for L-F soldering.That's why I am trying to get some infos more from experienced people. Some L-F (SAC or SACX) cored wires vendor
