Hi CJ, if you need a rework station for any SMD's (fine pitch, BGA's, chips, SOT, ...), maybe you should also check ERSA that offers rework stations with computer controlled thermal profile (meaning you can apply a typical profile for each typical re

I have never used the Vitronics but have pretty extensive experience with the Electra as well as Ultra-Pak and econ-pak from electrovert. I ahve been impressed with these machines for their durability and ease of use. A laminar flow with the rotary

Hi Rob, I guess the ratio between chipmounter and GSM is very much depending on the chip to ICs ratio. This is product dependent. We use 2 HS50 to 2 GSMII, 5 S20 to 2 GSMII, 3 Sanyos to 2 GSMII, and 2 CP6 to 2 GSMII. Are these ideal ratios ? Lean Ma

The re-use of any component has commercial implications as weel. If you check the data sheet for the component in question you will find the reflow profile, usually there will be a "Max No of Reflows". I have never seen this number higher than 2. If

Hi Ken, I know this doesn't help in the immediate timescale, but isn't avoidance the best form? can you trace the cracking to a process issue (Solder profile, shock damage, handling damage, probe/ATE damage)or a chip cap manufacturing fault? I can'

Hi All We have two boards that we produce which are chip on glue. For this we use KME BD12's which use air to dispense the glue dot on to the board. This is not ideal as the glue dot size differs as we go down the tube causing us quality problems.

I am curious if anyone can help explain to me the cause of an effect we are seeing with some failed caps. The parts have been found to be cracked and in most cases are hard failures (capacitance well out of spec and DCR less than 100 ohm or shorted)

Hi all, been recently wave soldering some pcbs with no problems and have now noticed what looks like blue residues on some solder joints. We have been running this product for around six months and this is the first time we have seen this. It is rand

I was wondering if anyone has had any experience with either the Esec Micron 2 or the RD Automation CDB-50? We currently have a Micron 2 (1997 build). We are using it for small batches of flip chip. We use the waffle pack feeder not the wafer loader.

Grant, I just have one question. Why would you go from a Mydata machine to a Fuji XP? You seem to be sacrificing component range for raw chip output. Wouldn't one of the multi-function machines (0201 - 45mm with similar speed) on the marketplace
