I've used VJ Electronics Summit series of rework machine. I liked the programing interface. You can used canned scripts for basic removal/replacement processes or you edit/write your own if you want a customized work flow. The machines are very ope

I had a DOS Heller 1500 a looooong time ago so my memory is fuzzy. That being said I remember there were some weird options in some of the configuration menus. I don't remember the names, but its were you would set the alarm points, you could manual

Fuji makes great machines, just depends on the local support If you are not doing anything special I'd probably just go with the I-pulses as you'll get a lot more machine for your money, and have some left over for inline AOI/SPI or look at somethin

Yes I would, most of our old Yamaha machines (before 2005) will do 30-35 microns @ 3 sigma with the fine camera option. Our Jukis with His res camera's will hit it too. You should be OK with most things after 1997 with the right camera choice (whic

Hello Hai, The first step is to determine where in the process the bubbles are being generated - either during coating or during curing. You can easily check this by letting a few boards air dry (no oven) and comparing them to the oven-cured ones. I

Guys, I have been down this road also spent a lot of time working on this. Electrolytics often are difficult to solder like this. For the sake of testing, try a water soluble more active flux as an initial test. IF you compare hand solder wetting the

As a CM, we don’t have a lot of input on the PCB layouts we receive. Some engineers/software packages output the paste layer 1 to 1, some do an across the board reduction, and some set each part up individually with different reductions per footprin

Solder paste flux is main contributor, Lead termination chemical-oxide by products and PCB Plating-Chemicals. Reflow profile would have very limited if not no impact really unless is way off. Paste volume control and Stencil design plays a big part
