Knowledge of blind hole board production in circuit boards Apr 26, 2024: 　　　　With the development of electronic products towards high density and precision, the same requirements have been put forward for circuit boards. The most effective way to increase PCB density is to reduce the number of through holes and precisely set blind holes and buried holes to achieve this.　　1. Definition of blind holes　　a: Compared to through holes, through holes refer to holes that are drilled through each layer, while blind holes are non drilled through holes. (Illustrated, eight layer board examples: through hole, blind hole, buried hole) b: blind hole subdivision: BLIND HOLE, buried hole Buried HOLE (outer layer not visible); c: Distinguish from the production process: blind holes are drilled before pressing, while through holes are drilled after pressing.　　2. Production method　　A: Diamond belt:　　(1) : Select reference point: Select a through hole (i.e. a hole in the first drilling strip) as the unit reference hole.　　(2) Each blind hole drill belt needs to select a hole an

PCB Layout and Design Services.Introduction to OSP surface treatment process for circuit boards Apr 25, 2024: 　　　　OSP is the abbreviation for Organic Solderability Preservatives, also known as copper protector. Simply put, OSP is a chemical method that grows a layer of organic film on a clean bare copper surface. This film has oxidation resistance, heat resistance, impact resistance, and moisture resistance, used to protect the copper surface of circuit boards from oxidation or vulcanization in normal environments; But in the subsequent welding high temperature, this protective film must be easily removed by the flux quickly, so that the exposed clean copper surface can immediately combine with the molten solder to form a solid solder joint in a very short time.　　1. Process flow: degreasing → water washing → micro etching → water washing → acid washing → pure water washing → OSP → pure water washing → drying.　　2. Principle: A layer of organic film is formed on the copper surface of the circuit board, firmly protecting the fresh copper surface and preventing oxidation and pollution even at high

medical electronics printed pcb.Why do PCBs use sinking gold plates Apr 24, 2024: 　　　　To solve the above problems of gold-plated boards, PCBs using gold-plated boards mainly have the following characteristics:　　1. Due to the different crystal structures formed by gold deposition and gold plating, gold deposition will appear more yellow than gold plating, resulting in better customer satisfaction.　　2. Due to the different crystal structures formed by sinking gold and plating gold, sinking gold is easier to weld than plating gold, and will not cause welding defects, leading to customer complaints.　　3. Due to the fact that only nickel gold is present on the solder pad of the sinking gold plate, the signal transmission in the skin effect is in the copper layer and will not affect the signal.　　4. Due to the denser crystal structure of deposited gold compared to gold plating, it is less prone to oxidation.　　5. Due to the fact that only nickel gold is present on the solder pad of the sinking gold plate, it will not produce gold wire and cause slight shortening.

high mechanical performance PCB.PCB board maintenance knowledge Apr 23, 2024: 　　　　1. Annual maintenance knowledge:　　1. Clean the dust on the circuit board.　　2. The electrolytic capacitor capacity in the circuit board is randomly checked, if the capacity of the electrolytic capacitor is found to be less than 20% of the nominal capacity, it should be replaced, and the general life of the electrolytic capacitor should be replaced for about ten years to ensure the working performance of the pcb.　　3. For high-power devices coated with heat dissipation silicone grease, check whether the heat dissipation silicone grease is dry and solid. For dry and solid devices, remove the dry and solid heat dissipation silicone grease and apply new heat dissipation silicone grease to prevent the high-power devices in the circuit board from burning out due to poor heat dissipation.　　2, seasonal maintenance:　　1. Clean the dust on the circuit board every quarter, use the circuit board special cleaning solution for cleaning, after cleaning the dust above, dry the circuit board with a ha
