The performance and technical requirements of the circuit board of the PCB processing manufacturer are related to the structure type and selected substrate of the circuit board. Different types (rigidity and flexibility), different structures (single -sided, double -sided, multi -layered, or without blind holes, buried holes, etc.), PCB boards with different substrate materials, have different performance indicators. Its performance level is usually divided into three levels according to the range of product design. PCB manufacturers describe the different degree of products in complexity, functional requirements, and the frequency of testing and testing. The acceptance requirements and reliability of different performance -level products are increasing according to the level of reliability.

Level 1 -Ordinary Electronic Products: Mainly consumer electronics and some computers and its peripheral equipment. There is no strict requirements for the appearance of this type of PCB board. The main requirement is that there should be complete circuit functions to meet the requirements of use.

Level 2 -Dedicated service electronic products: including computers, communication equipment, complex commercial electronic equipment, instruments, instruments, and some products that are not very demanding for use. This type of product requires a long life, and has requirements for uninterrupted work, but the working environment is not bad. The appearance of some products is not perfect but the performance should be intact, and there is a certain reliability.

Level 3 — High -reliability products: including equipment with strict continuous performance, equipment that does not allow stop time during work, and equipment for precision weapons and life support. The PCB processing printing board not only has complete functions, requires working uninterrupted, and can work normally at any time. It has a strong environmental adaptability, and it should have high insurance and reliability. For such products, there should be strict quality assurance measures from design to product acceptance, and some reliability tests should be done if necessary.
