Welcome to RoHS. Or, at least, to the version of RoHS that I've had to deal with since I started with my current company. Blowholes and pinholes seem to be common in PB-free manufacturing. At least, they have for me here. I also note that IPC has

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

Listen, why are you guys comparing air conditioning to wave soldering? There is no way your house will get that warm, unless it catches fire - I would know cause i smoke in bed way too much. Anyway, my two soltecs run 16 hours a day. on 3rd shift

Hi folks, I've been bouncing off of MyData technical support for some time on an issue with a MyData machine. Seems that this My9 likes to skip an 0402 placement at a rate of ~ 1000/million. Profile: MyData My9 Mechanical centering Midas only

Hello AJ, The previous answers are correct; Sn has seen a spike in price ever since RoHs was implemented. Furthermore, the other alloys that have been used to replace Pb (because of RoHs) have also seen an increase in price. Sadly these material rep

Does it give any more info about the error? Is this in the stage after you've hit run, it says "initializing" and it is counting up on the screen? Usually it gives a little more info, although it can still be cryptic. I have run into it stopping w
