PCB board repair refers to the bringing the physical damage which has been done to a PCB-namely pad or trace lifting, laminate repair, eyelet replacement to name a few-back to a point to where the printed circuit board can function based on the original design requirements. Printed circuit board repair skills and processes require lots of patience and a high degree of hand-eye coordination.
Single Lead Electrocardiogram CPU Motherboard Repairing Solutions include obvious broken components checking, faulty soldering and adjustable resistor: Find obviously damaged components Carefully look at the components on the CPU motherboard to see if any are damaged or burned. Usually, it is easier to see capacitor expansion or MCU cracking, triode breakdown and burnout, or a…
Faulty Medical Ventilator Controller Board Troubleshooting can be carried out by below methods based upon the technical personnel experience and limited terms: Cleaning and descalingAfter the Medical Ventilator device is used for a period of time, a large amount of dust will be adsorbed on the surface of the controller board. This dust will cause…
Various methods can be taken for Toshiba Computer Tomography Device Mainboard Faulty Inspection, hereby we would like to introduce some of the most effective ones for your reference: Various possible causes are inferred according to the working principle of the Toshiba Computer Tomography and the fault situation, and then it is difficult to eliminate one…
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…
