Sophisticated computer analysis ?

It is a well-known fact that the high tech electronic equipment used in the marine/off-shore filed demand superior technologies and sophisticated computer analysis. Accordingly ACSPL has installed a State-of -the Art fully computerized electronic PCB repair station which has got latest diagnosing tools, software and programming devices for fast repairing & trouble shooting of digital , analog, mixed signal, microprocessor, micro controller , EPROM, RAM , SMD, multi layer of various marine electronic control systems. Trouble- shooting a faulty electronic circuit is an art. The successes depends on the knowledge and experience of the engineer on the job and with this work station as a tool can give you the best in the shortest possible time with no compromise on quality and only better result.

Why does PCB repair ?

It's not always practical or cost effective to return boards to the original manufacturer for repair. This is especially true if the equipment is obsolete or the manufacturer has ceased trading. Most of the manufactures upgrade their product periodically and stop production of old model PCB. Hence most of the marine PCB is not available with original manufacture for replacement. Even if PCB is available abroad, import will take long time which would not be afford by ship schedules.

Why do PCB's Fail ? Functional failure of components, Improper operation, variation of power, environmental conditions, component ageing, damage to PCB tracks are some of the common reasons of PCB failure. Survey indicates that normally most of the new systems breakdown within the first ten years.

What are normal faults encountered in a PCB repair environment ?

Functional IC failures, loaded power supply, input/output pins shorted to VCC or ground, multiplier shorts, faulty de coupling capacitors, Bus faults, Fan out faults, Open/Short of passive devices, Track shorts/opens are some of the most common problems encountered in a PCB. The trouble with doing something right the first time is that nobody appreciates how difficult it was. -- from "Fortunes"

Conventional methods and its limitations

Service engineer uses various methods and tools of testing which include conventional equipment's like Oscilloscopes, Multi meter and logic analyzers. General testing Out-circuit testing is performed which may either require the PCB to be connected to the original circuit / equipment so as to get the necessary input signals. This way the whole / entire equipment is required for the testing and may become cumbersome. Another conventional method needs to remove the PCB and test the components separately. This may cause some major damage as removing and re-soldering has to be done and even the PCB tracks as well as components may get damaged.

How we at AKSHAY CONTROLS & SYSTEMS PVT. LTD. are different ?

In order to avoid all the above-mentioned problems we in our labs try using new methods. Our methods are the in-circuit testing ones, which do not require removing any components from the PCB. Moreover we at our labs use an intelligent in-circuit tester that tests the PCB at component level. It stimulates appropriate inputs to a device, measures its output response and declares whether it is functionally good or bad. Even complex natured LSI and MSI IC's are tested and the process is less time consuming with good results. Here we can repair the PCB's even with out circuit diagrams.
