I would say yes. I don't believe that ICT will every be replaced by boundary scan. Now on some assemblies, boundary scan is viable and certainly a better choice considering test access constraints. But ICT still will play a vital roll in the futur

Lots of papers out there on HiFreq circuits and the effects of solder paste residue. Google Dr. Karen Tellefsen. Simple test...take a "failed" board, remove the residues, test again. Has the problem gone away?

But the problem with flying probe is the cycle time. I'm not sure if there is a flying probe out in the market today that can match the cycle time of the conventional bed-of-nails ICT.

They are faster today, but still not up to fixed-pin machine speeds. They tend to be 7x to 10x slower. Any of the machine suppliers can run a test evaluation and give you a report on test coverage and test times. There are techniques to make them fas

Yes, sure. In fact in some applications ICT is coming back. Mainly due to the fact that more and more SMT discrete components have no markings, so AOI cannot tell you if you have the correct value on the PCB. Fixed pin or flying probe ICT is a valuab

If you are running FR4 PCBs and not something exotic like Kapton flex circuits, I would go with the Dek 265 any day of the week. You will find that Dek supports the fully automatic printer much better than the semiautomatic printers like the 260, 24

I am looking at buying a pick and place machine to assemble the circuit boards we make. Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

You must thermally profile your circuit boards with a data-logger and thermocouples. Just putting in oven set points and looking at solder joints is not enough. Reference IPC-7530
