During the refill of the solder bath in our mySelective 6746 selective soldering machine the RTD for the solder bath has become defective. There is no part No and the manual doesnt specify. Does anyone know which RTD is the correct one and possibly k

Conductivity is the recprical of resistivity. So, ... * 10 uS = 100k ohm * 5 uS = 200k ohm * 2 uS = 500k ohm We're unsure of the units of your conductivity of "1,566 uS/cm". Also, is that one thousand, five hundred, sixty six?

They are panels of 2 and we break them before ICT. Have to say that we do not check that 100nF cap in ICT since it's parallel with some eCaps.

Do you have to 'break' the pcbs from a panel or biscuit or are they individual pcbs form the start ? Poor pcb separation techniques or processes will damage ceramic caps.

After a detailed check the cracking was most likely from the ICT and a variation in the length of the probes (due to wear and tear) that press down the PCB. I am very certain that was the reason.

Does anyone have experience with the zsct1555 timer chip made by Zetex? I can't seem to get it to oscillate properly. My values for vcc and components are as follows: Vcc=1.5v Ra=220 ohm Rb=3200 ohm Ct=100uf OR..... If you know of any other chips

Pick & Place > Wave-solder > other parts > test > conformal coating Is there any production error that could make a ceramic cap conductive? PS: want to add one point: The caps don't seem to be cracked. We changed a few 100 and didn't notice any bro

This is my first circuit board that I am attempting to build and need a little help. Not exactly sure what is going on but maybe one of you guys could give some input. I am attaching the electrical diagram I am using. Everything thing seems to be wor

Guessing at the meaning of your description of �res., fmf, .100, 3010, 1, S�: * res - Resistor * fmf � �mf� tells you �metal film� �fmf� tells you �flame metal film� type * .100 - Precision tolerance 0.1%, although it could be power rating. * 3010 �
