Hi All, I have designed 4 Layer PCB with one 28 pin QFN PKG. I have got complaint from Production that the pads which connected to thermal pads (gnd) thru trace is bridging with solder and because of this bridge, pins are not getting soldered prope

Likely, but if your dross production is mostly due to pumping a high wave, or, due to a system that is configured to produce a lot of dross from the solder wave return to the pot, pump shaft interface or an aggressive chip wave, then maybe wax will n

After 16 years in the industry, I have honestly never heard of putting wax in a solder pot. Anyway, I do have some experience with Treiber wave solder machines, and as I recall, the air-driven pumps are a nightmare to service. First of all, make su

Hi All, Is there any way to use ROHS6/6 [Non-leaded] BGA device in Non-ROHS reflow [240 Deg C] temp. environment. I need to do this because Leaded [ROHS5/6] device I was using is obsolete and Non-leaded[ROHS6/6] drop-in-replacement part is availab

Thanks for the help guys. Nice to think I was basically on the right path. PCB manufacturer has finally conceded the barrel defects and is remaking the PCBs. We are big on pre-tinning the leads of TH connectors as well as providing some good pre

What software version and build are you using, and were you lucky enough to get a manual for it? How big are your moduals and what is your component density like? Setting up a MV3-L for IPC 3 will take a serious investment in time for a operator wi

On the bare boards, no paste, just a bare FAB board. We get them from a PWB manufacturer and inspect them to IPC-A-600 and then ship them to another manufacturer to populate them and we then inspect them to IPC-A-610. I have written several program

I saw a lot of people read this post but no one answer me so I thought someone may be interested to know how this thing works. My problem was in the "F4G_LINE.CFG" file. The "RTM" heading had a "NO" when it should have been "YES". This will make wha
