[0002] Instruments refer to the general term for instruments that display numerical values, including pressure instruments, flow meters, and various analytical instruments. Instruments are widely used. When instruments leave the factory, they need good testing technology to ensure that unqualified products can finally enter the market with qualified products.

[0003] Instruments often run well and badly, and most of these problems are caused by poor contact or cold soldering. For this situation, the knocking and hand pressure methods are usually used. Use the handle of a screwdriver to knock on the edge of the printed circuit board and the components on the vibration plate, and use a screwdriver or tweezers to press on the suspected components to observe whether the fault phenomenon changes. If there is a change, it means that the component has a problem. You can also use your fingertips to gently press the suspected components or leads, and it is possible to find cold soldering or desoldering points; pressing some parts of the circuit board can often quickly find the faulty part, such as where the printed circuit is broken. Press the suspected integrated circuit with a rubber, turn on the machine to see if the fault changes. If there is a change, it means that the integrated circuit has a cold soldering problem.
