1.Significantly improve product quality and reliability When the Flex-Rigid PCB is applied to the car, the connectors and solder joints can be reduced, which can reduce the potential risk of electrical failure. The performance and reliability of automotive electronic control systems will be proportional to the reduction in connectors and welded joints. 2.Reduced costs due to […]

FPC In order to prevent non-conforming products from being shipped, 100% inspection is a common practice. Every product produced is inspected and judged as qualified or unqualified. Qualified products will be shipped, and unqualified products will be left for repair or scrap. All this is simple and straightforward. Regardless of the errors of the inspectors, […]

The application of HDI is becoming more and more extensive in the electronics industry, especially under the current trend of miniaturization of electronic products. For the same product, choosing HDI designs with different structures will have a great impact on the cost. The above figure shows a 10L PCB built on a standard multi-layer process. […]

1. Determine the unit of calculation for production capacity Due to the wide variety of enterprises, the products and production processes of different enterprises are very different. Before calculating the production capacity, the production capacity measurement unit of the enterprise must be determined. (1) Input and output Production capacity is closely related to input and […]

1. The core of the high-density interconnection board (HDI) is in the via The circuit processing of multi-layer PCB is no different from single-layer and double-layer. The biggest difference lies in the process of vias. The lines are all etched, and the vias are all drilled and then plated with copper. Everyone who does hardware development […]

The production of PCB is very complicated. Taking a four-layer printed board as an example, the production process mainly includes PCB layout, core board production, inner PCB layout transfer, core board punching and inspection, lamination, drilling, and hole wall Copper chemical precipitation, outer PCB layout transfer, outer PCB etching and other steps. 1.PCB layout The […]

Why do you want to panel, that is to say, what are the benefits of panel? 1. In order to meet the needs of production. Some PCB boards are too small to meet the requirements of making fixtures, so they need to be put together for production. Improve the welding efficiency of SMT patches. It […]

 First,What is the FPC tube? FPC is also a flexible circuit board, which is a semi-rigid plastic tube. The main material is made of polyimide or polyester film, which has high reliability and excellent flexibility. It is characterized by high wiring density, which can effectively reduce product volume and softness. As a three-dimensional space assembly work, and […]

1. Outer circuit design rules: (1) Welding ring (Ring ring): The welding ring of the PTH (copper-plated hole) hole must be 8mil larger than the single side of the drilled hole, that is, the diameter must be 16mil larger than the drilled hole. The welded ring of the Via hole must be larger than the […]

The development of the downstream PCB industry promotes the growth of PCB ink demand Printed circuit boards are the basis of electronic information products. Therefore, the application fields of printed circuit boards involve almost all electronic products, including communications and related equipment, computers and related equipment, consumer electronics, automotive electronics, aerospace electronics and other industries. […]

As we all know, circuit board cleaning technology has a very important position for pcb copy boards. Since it is necessary to ensure the cleanliness of the circuit board itself in order to accurately scan and generate the file map, the cleaning technology of the circuit board has also become an important “technical activity.” Four […]

Via is one of the important components of multi-layer PCB circuit boards, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB manufacturing. Simply put, every hole on the PCB can be called a via. 30% to 40% of the cost of plate making. Simply put, every hole on […]
