PCB Design / Redesign / Repairing (Computerised)
ACSPL is specialized in MARINE ELECTRONIC PCB design, repairing & redesigning or reverse engineering. Electronic PCB are integral part of any marine equipments and systems. As this products are keep on updating, manufacturers discontinuing old PCB’s.Quite often, because of this reason ship owners are force to replace complete equipments. This required considerable amount of down time and money. We have group of talented R & D, design and service engineers who are specialized in marine electronics.We have successfully completed numerous assignments in INDIA and abroad.
Marine PCB Designing
Electronic PCB are integral part of marine equipments and control systems. Hence when a marine system is non operational often end up with a defective PCB which in no more in production with OEM, while e veryth ing else is OK. If PCB is damaged beyond repair or unavailability of spares being too old... Solution is to design a new PCB for the same function so that original equipment on board can be used …
Marine PCB Repairing
When a marine PCB is defective, do not scrap it unless expert so. We have a computerized multi-functional repair station. One million IC data available. Whenever we repair an PCB, we leave a copy of data in our system so that next time same type PCB repairing is faster. We can program test jig for your PCB testing. Computer mapping for fast repairing. In circuit testing of Integrated Circuits (IC) IDDE (Integrated Device Development Environment)
Marine PCB Reverse Engineering / Redesigning
Redesigning or Reverse engineering is an engineering process which used to generate electronic circuit diagram from the PCB. This is the reverse process of designing and it is used when no details of PCB are available them is the need to replace an obsolete board that is no longer available from the original manufacturer (OEM). When a ship is become old by ten years, OEM stop production or modify the electronic circuits, hence replacements such PCB may not be available for replacement...

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, EP ROM, 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 upgr ade their product periodically and stop production of old model PCB. Hence most of the marine PCB is not available with ori ginal manufacture for replacement. Even if PCB is available abroad, import will take long time which would not be afford by ship schedules.
Why does 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 norm ally 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 decoupling 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, Multimeter and logic analyzer 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. An other 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 a void 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.
Reverse Engineering of Marine PCB
The need for REVERSE ENGINEERING OR RE ENGINEERING PCB's comes about for a variety of reasons chief among them is the need to replace an obsolete board that is no longer available from the original manufacturer (OEM). When a ship is become old by ten years, OEM stop production or modify the electronic circuits, hence replacements such PCB may not be available for replacement. Now a day’s most of the OEM is giving block diagram instead of circuit diagram. This block diagram is not useful for servicing of PCB’s.Often companies employ us to reverse engineer their own designs, because they have little or no documentation for their own product or their current design firm or manufacturer refuses to release design details and manufacturing files.Another reason is cost. Some boards are considered proprietary by the OEM when in fact they are not; they are just too expensively priced. Re-engineering a PCB assembly can provide improved or added performance to an old process.New and improved components and techniques may be utilized during the reverse engineering process improving operations, maintenance and support. PCB reverse engineering is done by hand. We also use computerized scanning programs because we have found that too much of a circuit can be missed and you end up doing it by hand anyway. We believe that doing the job right the first time saves time and money. A design engineer checks the emerging schematic to see that it makes sense. All too often, simple common sense is all that is needed to avoid costly errors.
