Good Idea. I think there are many Bad apple used equipment dealers as well. We should track them as well. Every bad apple needs to be dealt with. OEM must make money to survive and support systems. But I must tell you for example I have found many th

Good points Ken But the reality of the matter is that we are selling off some fuji equipment that even though it is 1994/1995 still has a sale value of 45-65K Each. I am replacing it with faster systems with 0201 specs. With the margins so razor thin

Gee Steve, it's nice that someone remembers me. Yes Dave, I noticed that you did too. I feel guilty about having become a "lurker" when I manage to look in now and then but the pressures of what they expect me to do around here (for no more money!)t

Blimey that's a problem and a half. Water Solubles will look completely different residue wise than No Cleans, pending age and solids contents No Cleans will go white powdery - watersolubles will stay oily Alternatively process reworked PCB's through

These boards also were above liquidus for 75 seconds, and the customer puts the boards thru extensive thermal shock and stress testing. An Alpha Applications engineer told me that because the boards were above 183 degrees for 65-75 seconds that the i

Wait a minute I thought I said Celestica and a few others have done the Engineering evaluations on a list of 10 top solder paste's and Indium SMQ92J and Kester's R560&562 came out on top. First you say 'don't trust all of the so called experts on thi

We theorize a secondary [bottom] side BGA can be wave soldered with planning. Issues are: * Keepout between the BGA and one side of the board that is clear of PTH parts requiring wave soldering, so to support the fixture. * Keepout around the BGA. *

Hi, I have a soldering problem with a header SMT straight single row of 8 pins. It's a samtec #TSM-108-03-T-SV-P (P&P). The first problem I have is an allignement one. I do not use alignement pin for now but I expect to use it. Concerning solder

Tony, Be very careful with used equipment dealers. Make suer they have a comprehensive remanufacturing plan for the equipment, that it is calibrated the same as it would be from the OEM, and that the staff that will install and maintain it are fami

I have seen this affect on Immersion Tin and OSP. 70 to 90 % of the solder wicks to the lead and forms a "single" homogenous solder mass. This even though the pad was 100 % covered with paste... Evaluated different solder paste...did find variatio
