sorry. re-read your post. The problem is the home sensor relative to the home pulse. You're catching the wrong home pulse. a 10mm offset sounds about right for a 360 degree error. You need 50% +/- 15 % to ensure you always zero to the same phys

Can't say too much about the solder joints issue, but about a decade ago we did have a lot of problems with resonators being damaged by harmonics from Ultrasonic board washing & Ultrasonic welding. However this mostly manifested itself as cracking i

HI all, which is the last "though" about the max Pb % allowed/acceptable into a Pb Free Alloy ? For istance inside : - HASL Process Solder Pot Alloy - Wave Solder Pot Alloy ( 400Kg mass average) - Static Wave Solder Pot Alloy - Etc IPC-J-

It's easier if the Operator does keep an eye over that, HOWEVER, if you really think about it, you are allowing the very person who ran the board monitor the quality of the board (again, re-visiting AOI errors, and what they allow and don't allow). A

Morning Mike, We use Pb63/Sn37, Alpha Metal alloy. Solder pot is at 250 C. The profile of board after Preheat about 100 C, Lambda Wave about 220C (use both Lambda and Chip wave), DWell time 2.1s ~ 3s. Conveyor speed 1.5 in/min. We run by bare board a

Have you complained yet to MuRata? You are talking about the same bluetooth module, aren't you. I hope everybody having trouble with module complains to them. I don't believe they put all the cautions and warnings about reducing the deltaT on the da

Guy's another question, how about any recommendation what type of adhesive to use as underfill for BGA during lead free process? Currently, we are only using Loctite 3609 & 3515 as adhesive we use 3515 as BGA underfill during normal leaded process s

I am sort of familiar with Specnor Tecnic myself from work at a previous employer. Yes, they are a group that split of from Electrovert and actually compete with Electrovert in their spares market. Don't know how that's legal but they seem to be doin

Haha Grant, totally agree about the software on the deltawave, why does every recepy not have its own fluxer set? Why does the fluxer speed doesnt change automatically when you change the conveyor speed? They really should think of kicking their so

Hi, it seems like you have some experience with the SM320... How do you feel about the reliability, and consistency of it? does it generate alot of error on a run? and what do you mean about feeders breaking the head? Also you're telling me that this
