Repair Voltage Regulator Control Circuit in Power Supply PCB Card system, both the direct error sampling circuit and the indirect error sampling circuit belong to the voltage regulator control circuit, but there are differences in the error sampling method. Among them, by installing a sampling winding on the switching transformer, then a voltage can be…
Rework Full Bridge Rectifier Circuitry in Medical Electronic Instrument PCB Repairing. The input voltage in the full-bridge rectifier circuit is 220vac, and the output is 300vdc, which not only changes the current, but also changes the form of current, but during the power up process, full-bridge rectifier diodes are easily damaged. After any full-bridge rectifier…
Medical Equipment Power Supply Circuit Board Repairing is critical since modern medical equipment is more sophisticated and the degree of automation is also significantly improved, it also has higher environmental requirements and failures during use, as a result of that, the incidence of power failures is higher. It mainly analyzes the power supply board fixing…
Computer Tomography Controller Board Faulty Diagnotise Methods can be categorized as below:Whether a controller board needs to be repaired or replaced, you must first determine whether it is faulty. As for how to judge? below methods have been summarized based on experience in actual work: First of all, Finding by malfunctional detection program: Large equipment…
Rehabilitate Medical Instrument Circuit Board Failure, such as some large-scale equipment such as Computed tomography instrument, Magnetic resonance imaging machines, etc. have their own programs that can detect the approximate root cause of the machine failure, and some circuit board failures can be detected by running the detection program. Printed Circuit Board on-line tester is…
Schneider Electronic Printed Circuit Board Restoration through Integrated Circuit Inspection will go through a series of steps to figure out the root cause; 1st of all, the suspected integrated circuit, according to the instructions of the manual, first check whether there is a signal (waveform) at the input and output ends. If there is no…
Maintain Fresenius Hemodialysis Machine Mainboard is a complete process and we have to repair it without schematic diagram and sometimes the root cause of the failure is not coming from the circuit board itself; A Fresenius hemodialysis machine reports Rinse failure F03 when the heat sterilization counts down to about 26 minutes. Press the Rinse…
Lithography processing technology refers to the key process technology of processing semiconductor structure and integrated circuit micro-graphic structure, and it is a kind of micromanufacturing technology which is applied earlier and is still widely used in the field of micromanufacturing. The principle of lithography is similar to photographic plates in printing technology, applying photoresists to…
Hereby we would like to discuss how to design Component in PCB Board Cloning through the standard procedures to get a complete and functional drawing: “Component placement” is the most important function of component pin connection processing. The component arrangement is divided into two-pins component arrangement, three-pins component arrangement, chip arrangement, switch socket arrangement and…
