Whoo-doggies Jason, you said a mouthfull!! (GRIN) Anyways, 'member what I said about me being a pack-rat? Guess what? I found some documentation that I've had for a while that does document the self-alignment forces that goes on when reflowing. I ha

Yes, I took the chuck off head 3, and made my own nozzle, which is working quite well. I can't set head 3 to vision, as this machine doesn't have the vision system. I set it to "IC" and that seems to work fine. I set mech alignment 1 and 2 to yes,

Hi Jason! I can probably find something documented for you, but the easiest way to convince your QA people is just to show them. If you have a board around that has some 1206 locations all in a row, print the board with paste and then plac

I am still learning the CSM84, but have gotten one board programmed and working. Now, I'm doing the next board, and need to use the mechanical alignment unit for a 22 x 22 mm TQFP. This chip is too large to clear the jaws on any head. Can the CSM h

Thanks! Well, the procedure in the book says to first calibrate the mech aligner with the beam sensor, but that exceeds the X travel. I guess you can just eyeball it off the nozzles and then use trial and error. While poking around on the machine

The pandemic has altered people's habits, causing a surge in demand for home electronic devices. This has swept the global chip supply and disrupted automobile manufacturing. The pandemic has led to the global shortage of semiconductors or chips, and

we experimented round pad for 0402, it improves chip self alignment and reduce tomb stone effects. On 0603, half round shape also gave guud results. G

Hi Manuel, most passives are chip components. These tend to self-center/align during the reflow process. However, you need to ensure that there is a uniform balanced solder paste deposit. I had tried few such ovals in earlier stencil designs and resu

Parts will self align using Pb free paste as well. If your parts are not self aligning with Pb free paste, you have a problem with either your paste or the oven profile you are using.
