Bismuth Solder alloys * Fatigue life is reduced when soldered to hot air solder leveled (HASL) boards. * Lead from Hot Air Leveling (HAL) coatings can diffuse through the grain boundaries of alloy. * Lead is bismuth alloys can form a eutectic composi

Bill This drives solder suppliers nuts, because it's not analytic: Dross inclusion testing can be conducted on the base solder in the solder pot and the virgin solder. Conduct this test by heating a sample of solder, contained in a clear beaker,

Hi folks, I have a conformal coating application where I need the coating to be UV stable for a number of years without any crazing or cracking of the coating. I have looked for such a coating and have come up empty handed. Much of the circuit boar

We were and still are having problems with magnetized nozzles on the HSP 4796. The problem was found when numerous parts were thrown after being placed on pad. It appeared to be picking parts up off the board after placement. Nozzles were pulled out

I have a product that has earthing/positioning holes, as they are to be used for earthing purposes they need to be free from conformal coating. This pcb is double sided. I have used spot/peelable mask to protect these holes. However when the conforma

I was wondering if anyone is using Fuji Flexa yet first of all. And if so what form of CAD socketing and documentation did you get? At the moment I run SMT programming (FujiCam) and Doc Control(Unidoc) so I will be seeing the whole picture. This will

I work for a small OEM. We have outsourced our SMT in the past and considering purchasing some used SMT equipment. My knowledge is limited in this area. Someone in my company has found a Zevatech 575 machine. Our run size is from 25pcs.to 500pcs.

The 575 was based on the 570 machine. The 570 was Juki's first laser centered machine. It can do 0402 and ICs with a pitch of 0.65mm or greater. The 575, was a re-vamped 570 that Zevatech came up with. Juki played no part in the 575. Zevatech ad
