A customer recently questioned our use of the EIA curves for derating SMT devices for increased ambient temperatures. The European method (CECC) is much more severe in derating power ratings of devices as temp increases, but there are differences in

Why/how are they getting mixed up? You should figure that one out and fix it. As far as some type of coding, I believe that the supplier of the part would have to do that in there manufacturing process. You can "light them up" with an appropriate p

Yes for sure you can use MV2F feeder on MV2VB, the only difference is MV2VB feeder have better design (more robust)then MV2-F type. For sure you have to take care do not mix "K" type with "Q" type feeders who are not compatible among them. Ciao.....

We do have a convection oven and no one has messed with it. I am the only one who can change anything. I have it set at Medium right now on a conceptronics oven. Could this be too high? We have not had problems in the past with parts moving off o

I am currently having a discussion with a pcb supplier about inadequate hasl thickness, we are measuring below 40 microinches of hasl when our spec calls for 100 microinches as the minimum. Our supplier came back with the statement the entire indust

We agree. Colin Lea showed that HASL less than 2 microns [80 uin] thick has limited shelf life and that shelf life gets worse as the HASL gets thinner. Unless you do not need shelf life, consider sticking with 100 to 500 uin. There is nothing wrong
