Hi folks! I have ran into a problem which has me baffled and the extra 20
ounces of Coke I consumed this morning didn't bring about any better
thought clarity so I would like to bounce the problem off the minds of
TechNet. I have been attempting to hand solder a chip resistor (50 x 100)
but have immediate cracking of the resistor across the width of the
component. The resistor is either Aluminum Nitride or BeO (I'm still trying
to find out which material). And yes, we are using proper soldering
technique(s) and the resistor pad geometries are our standard dimensions. I
know that the typical resistor body material is Alumina. Has anyone had
good or bad experiences in hand soldering AlN or BeO resistors? Have I run
into a material flexural strength issue?
