Repair Medical Equipment Circuit Board Without Schematic Diagram is a very traditional situation in the process of medical electronic equipment pcb board maintanance;
In daily work, every one of us engaged in controller card troubleshooting will encounter this difficulty, that is, the equipment to be repaired, especially imported medical equipment, often does not have medical electronic circuit board schematic drawings in hand which can be acquired by pwb reverse engineering.
With the rapid development of science and technology, all kinds of advanced medical equipment are emerging endlessly, the functions are increasingly perfect, the degree of electronicization and automation is constantly improving, and the electronic circuitry scheme structure is more complicated.
And these precision equipment will inevitably break down with the use of time. It is often very difficult to inspect and repair such instruments without printed circuit board schematic drawings. When it is sent to the manufacturer for repair, the entire circuit board is often replaced.
Inquire carefully and observe the failure phenomenon carefully. Start with simple and find out the peripheral failure points.
We also need the above four elements to rehabilitate medicalelectronic equipment.
“Look” first is to see if the equipment’s motherboard being repaired has any artificial appearance damage, and whether the environment and maintenance of the equipment are clean.
“Smell” is to smell if there is any odor such as burning,
“Ask” asks the operator about the service life of the device, if there were any threats before the failure, and if there were any errors in operation.
“Cut” This is the first step involved in specific control board maintenance. First, check whether the positions of the adjustable knobs on the instrument panel are normal. Second, check the power supply insurance, power terminal board, stabilized power supply, external connection cables of the host, and plugs. Whether it is intact, correct and not loose. Many instrument failures are caused by the above reasons.
