Measured the pot temprature independantly from the software (268C/514F from moving wave). We are using Dross Inhibiter Tin/P Regenerator from BLT. Monthly sample checks are carried out on the solder bath and are all within limits. It will be hard to

I haven't been in a bad enough situation to try it yet, but I had a conversation with Alpha Metals when we started doing 0.4 mm pitch and they mentioned that if we got into a situation like yours we could send them a board and they'd modify the artwo

Hi all, We have two Heller ovens, a 1700SX and a 1700D. The 1700SX has the profiles made so when you load them the zones turn on in sequence. First zone top and bottom are on when the profile is loaded then the next (top and bot) start to turn on as

I would agree with innova's suggestion of Marantz. I've seen 3 different AOI machines implemented into our shop, and you really have to consider the ease of use, and possibility of defects that operators can introduce. AOI's, theoretically, look good

We used to have a Nuclean 324 that was running closed loop with a DI water recirc system. We also had problems with foaming that was solved with a relatively simple fix. We bypassed the final rinse solenoid so that it was always running. This allo

This issue can be common on such large size boards. The newer laser we use today to cut stencils are generally accurate to +/- 5microns X and Y. Probaly way more accurate than your board which will have a +/- into thousands of an inch. Try send a boa

The PCB has 9 QFNs, distributed arround the whole board, but the ones in the edges are the ones with the problem. My stencil is 0.005" (I use to have a 0.006"), yesterday I realize after talking to my vendor that the stencil is manufactured in 2 step

..... that's very strange. If there were any risk of de-lamination then it would of occurred during the reflow process, surely. Unless the through hole department are using heat guns or wave sodler? I doubt if the sales or planning team are happy if

I purchased and am setting up a used QSA30. It has been a little frustrating but I finally have an almost program. The isse is that I can not generate a placement program because it says that the ANC is not registered. I can look at it on the sy

To check the airflow for your exhaust, use a manometer. Testo makes pretty good low cost models. Your machine manufacturer should be able to tell you what the requirement is or it's in the manual under setup. If it's a Vitronics Delta wave, I can
