Topic: What is BOST? How is ICT different from Bed of Nails?
Description: Can someone explain to me what is BOST in non-jargon terms? For example, BIST is "Built in Self Test-essentially builds tiny tester models onto the integrated circuit so that it can test itself. " I know what is BIST, but not sure of BOST. --- Also some sources use "ICT" and "Bed of Nails" interchangeably while others distinguishes the two. I specifically want to know what role ICT plays in bed of nails testing. Thank you!

What is BOST? And what role ICT plays in Bed of Nails Testing?
In plain english:

BOard Self Test (BOST) is similar to Built-In Self Test (BIST)
BIST works on a chip level while BOST will test the entire board.
BOST is not new. An X86 computer board runs a BOST otherwise known as a Power On Self Test (POST). The difference is that BOST's are usually designed to be more complete and are usually used or executed using remote software. ie. Like a large bank of multiplexors in a huge network can be troubleshot to the board level remotely.

Bed of Nails is simply a test fixture with probes that allow you to access the internal traces on a PCB. Functional tests (FCT) usually exercise the PCB from the card edge connectors. However, both ICT and FCT can use bed of nails fixture OR NOT, as in the case of fixtureless ICT on flying probe testers like Takaya or Scorpion of Teradyne/Genrad Pilot.

Do you need more info ?

Pin point II is a combinational tester. It can be used as in cct tester and also as a functional tester. Tester is equiped with test view software. System has latest features to meet PCB testing requirements both digital and analog. System has build in virtual instruments for analog testing. It has rich component library and the OEM promises to upgrade component library periodically.
