This we obviously need to fix! Thank you for finding it, Dave. re baronial mansion - afraid not. Nor do we have shrink wrap licensing that requires your services as a "towel boy". As for documenting errors, there is a hook - in most, if not all

I assume that you are referring to classroom or hands-on training facilities. Unfortunately, I do not have or know of such a comprehensive list. Our materials go worldwide, but generally they go directly to the manufacturer. In a couple of cases th

Of course recognize off the top that I have a certain bias :-) - and the choices are somewhat limited if you are looking for off-the-shelf product. There is also NO independent agency that I know of (i.e. an electronic training "Consumers Report")

Yes, some testing of soldering chip capacitors onto ceramic substrates with high temperature paste proved successful. Die attachment can be achieved using this technology as well. The underfill of the die becomes a critical factor in rework potentia

For any rework machine a good optics system is important. A look-up look down is used for BGA components. 30X magnification is required for flip chip, MicroBGA and fine pitch QFP placement. Digital cameras are not required, CCD have a good enoug

There is no IMC composition can be identified in phase diagram of In/Sn. There are some compositions such as In3Sn or InSn4 cited in earlier literature. Those composition should be regarded as approximate representation of solid solution of In/Sn. I

Regarding solder paste printing, many books available on the market all have some sections addressing this topic. Unfortunately, as of today, solder paste printing has not been the main theme of any book yet. I consider the better sources of informat

Only used adhesives once and it was a disaster. I don�t rearly have much experience but the real problem is everyone wants to compare adhesive with solder and they will not give the same results. There is a good book on adhesive check out my book re

Bob We are just starting to look in to this process and have been told that it can't be done using a stencil to print the solder paste onto the PCB (of course it was by an equipment manufacturer trying to sell a paste dispnecer). Is this a far commen
