Hi Craig: I agree with muse. The problems almost always will show up later on duringg life cycles in terms of reliability problems. While the solder joints may look acceptable right after production there is no guarantee of meeting the reliability r

Hi JEM, We just made the very same upgrade you are looking to make on three machines. We purchased a new MY12 and upgraded our other three (My9 W/hydra, My9 No Hydra, and TP9-2U) from 2.2.4C to 2.4.4c. There are several changes and most of the

Hi First I think you have to analize your PCB design. Heavy weight components should be gathered on one side of PCB. As I think, if you want to reflow both sides simultaneously there might be a problem. A chance that large components will drop off

Dear All, We plan to setup an assembly line for our small volume production of PCBs (about couple hundred PCBs per week). The board has about 150 components (less than 30 types) and a few BGA and IC (majority is SMT, only few THT connectors). We hav

Hi, I believe you have classic gold imbrittlement here. With 80 microinches of gold you are way over the limit. You can try to reflow longer time and at a higher temperature. The gold does not melt into the solder joint. The gold dissolves into

Sounds like air pressure is set O.K. The next thing to check is that the platen surface that the x and y axis ride on is perfectly clean. After that, you should knock the camera off the platen and make sure that all of the small air nozzles are blo

I'm in the market, also, but vasilating over cost vs performance. I've also used both. In general, the LPKFs have more bells and wistles. On the LPKF S62, I love the tool magazine, and vacuum table. And, the fiducial recognition camera is great o

SWAG is prolly right. You can verify the tactile sensor by watching the machine carefully. When finding the stencil height, make sure the board goes all the way up and touches the stencil to trigger the tactile. If it doesn't, then something is wr
