Repair and Reprocessing of PCB Boards

Do you know? Whether it is a fully loaded assembled board or a bare board, as long as defects are found during PCB board inspection, cost-effective repair methods must be evaluated.

At the same time, it provides users with products with the same reliability as the original products. For simple circuit boards with only a few defects, it is usually uneconomical to reprocess them. However, many circuit boards have a high degree of complexity, and fully loaded boards may be expensive. At this time, it is more economical to reprocess the unqualified product to pass the test.

The bare board is usually not repaired because it will bring reliability risks to future assembly and use. Moreover, the price of bare boards is relatively low compared with assembled boards. Based on the above factors, in high reliability and military applications, repair and reprocessing of bare boards is not allowed, and reprocessing of bare boards can only be used for commercial purposes. However, the maintenance of the circuit board must comply with the original design requirements and meet the expected reliability and quality standards.

In addition, some used circuit boards need to be repaired and reprocessed. In most cases, the original components need to be removed and replaced with a new one. Usually you need to do this manually. For circuit boards with plated through holes, simple tools (such as soldering iron and capillary braid) can be used for repair. On the other hand, for SMD, a special reprocessing workbench is required, which relies on hot air reflow soldering equipment. In the repair process, a lot of chemicals are needed, especially in the process of cleaning, dehumidification, defluxing, wiping lubricant, freezing spraying to locate heat-sensitive components, etc.
