Invasive Electronic Sphygmomanometer Circuit Board Recovery needs to inspect the flip-flop trigger, strobes, register status, as well as the detection over discrete components and other components; The status of IC devices such as flip-flops, registers, and strobes is often closely related to the status of other devices on the PCB board. Therefore, it is best…
Epicardial Mapping Equipment Controller PCB Card Repairing can work on below aspects which include: 1, Interface IC chipset, 2, Buffers; 3, Latch; 4, Memory; 5, Counter; The interface IC chipset is a bridge between each controlling circuit board and the epicardial mapping equipment motherboard. Any information transmitted by the epicardial mapping instrument motherboard to the…
Endocardial Mapping Instrument Display Circuit Board Restoration can start from inspection over the electronic components: First of all, check the start-up of the crystal, especially the faulty circuit board in a vibrating working environment, which can easily cause the crystal pins to loosen with the inside, causing the crystal to malfunction. After confirming that the…
Repair Intracardiac Hexagram Mainboard by IC Online Tester can improve maintenance efficiency since it has a learning function, an offline test function, an LSI (large-scale integrated circuit) inspection and analysis function, and a VI (volt-ampere characteristic) curve analysis function. Test and compare the logic function of the integrated circuit chip through a large number of…
The general law of Electronic PCB Card Damaged Components Reworking (this can greatly improve the repair speed), the probability of electronic PCB card component damage in turn is: electrolytic capacitors, power modules, high-power transistors, zener diodes, resistors less than 100Ω, resistances greater than 100kΩ , relay, small ceramic capacitors. Circuit characteristics for repairing damaged capacitors…
Operational Amplifier PCB Board Repairing can be categoried as below steps:1st of all, judging the quality of op amps is quite difficult for quite a few electronic maintainers. Ideal op amps have “virtual short” and “virtual break” characteristics. These two characteristics are very useful for analyzing operational amplifier circuits that are used linearly. To ensure…
Engineer needs to pay attention to Failed Electronic Circuit Card Maintenance Order to find the shortest path to solve the problem, avoid random dismantling or desoldering which will cause the unsuccessful of motherboard maintenance and the failure will expand to more blocks or positions; Control board reworking is like a doctor seeing a doctor, but…
When Restore Broken Printed Circuit Board Without Schematic Diagram, most of engineers will feel it is very difficult and have no idea where to start, below we would like to introduce several methods which can help you effectively conquer this obstacles and find the most efficient way to do it: Be “chattered”To thoroughly understand the…
