Location India, Color Silver Pcb Testers, Design Standard

N pcbs boards, The past featuring printed circuitry had crafted to include simple ssi / msi / lsi and discrete pre-packaged standard components and used through hole dip packages that has the potential to be easily tested using a conventional board test ate either through a functional card edge design test or ict with a nail bed demonstration fixture or even clip on test of each device. The pcb technology over the years has changed a lot regarding package density and functional complexity. The new technology pcbs uses programmable logic devices plds, Field programmable gate. Arrays fpgas, Digital signal processors dsps and single chip micro controllers. Often a variety of devices are proprietary and with little information on the functionality belonging to the gadgets. Ball grid array bga packages make it harder to access the device pins. These pcbs are a great challenge to test and diagnose faults down to component level using a conventional ate system. The reasons are quite obvious, The device package density and the utilization of fpga / cpld / dsp devices as a substitute for standard devices.
