Some machines may require that the two locals be used to calculate a center point where some (probably most) just use them as a second positional identifier. The fiducials are programmed as just XY and just prior to placement the machine will read th

Hello all, I am looking for a general opinion on splicing tapes. It has always been my opinion that splicing was an after thought for the machines that did not allow feeder removal and replacement during machine operation. If the machine has the ab

We have tested SN100C for LF wave soldering process since August'05 and currently start production for a month ago. Initially we use SAC305, but due to the shrinkage cavities (micro-crack) we changeover to SN100C. In summary, SN100C did perform well

Let me give some information on the use of MS2. The average wave solder machine will use one liter per five day week per 8 hour shift. The usage can vary + or - 20%. Instead of removing 6 to 10 Lbs of dross every 3 hours you will have to remove 100 M

Samir, From experience, the only board test situation where tented via's have difficulty with contact is with a Flying Probe type tester. Otherwise, for traditional ICT, the force of the pogo pins, correct probe type, and fixture design should do th

So, if 45� is theoretically optimal for aperture fill, but 60� is better for defining fine pitch bricks, is 52.5� the best compromise for an all around design, or does it not work that way? I see blades with either one angle or the other but with th

I got some info about it last year. I could not justify ROI since this machine was way too expensive (same thing with Vitronics Selective machines). You need to see if this machine will increase your throughput or not depending on your products. Al

Temp. and humidity levels are dependant upon your chemical (paste and adhesive) specifications. Ballpark I'd say 70�F and 40%-45% RH are good targets, as our paste spec. says optimal ranges are 70-77� and 30-70 RH. As far as air quality, if you bui
