Perhaps we will wonder, the substrate of the circuit board has copper foil only on two sides, and the middle is an insulating layer, so do they not need to be connected between the two sides or multiple layers of the circuit board? How can the lines on both sides be connected together to allow…

Generally, there are several reasons for copper cladding. (1).EMC. For large-area ground or power copper cladding, it will play a shielding role. Some special grounds, such as PGND, play a protective role. (2).PCB process requirements. Generally, in order to ensure the electroplating effect or lamination deformation, copper is laid on PCB layers with less wiring….
1 Surface tension The cohesive force of tin-lead solder is even greater than that of water, making the solder spherical to minimize its surface area (under the same volume, the sphere has the smallest surface area compared to other geometric shapes to meet the requirements of the lowest energy state). The effect of flux is…
Blistering is one of the more common quality defects in the production process of circuit boards. The complexity of the production process and process maintenance of circuit boards, especially in chemical wet treatment, makes it difficult to prevent blistering defects on the board surface. Based on many years of actual production experience and service experience,…
The main factor that determines the quality and positioning of a board is the surface treatment process. For example, OSP tin spraying, gold plating, and immersion gold. Relatively speaking, immersion gold is for high-end boards. Due to its good quality, immersion gold is also relatively costly. Therefore, many customers choose the most commonly used tin…
The solder mask is the soldermask, which refers to the part of the printed circuit board that is to be painted with green oil. In fact, this solder mask uses a negative output, so after the shape of the solder mask is mapped to the board, it is not the green oil solder mask that…
Some substrates may absorb moisture and some of the resin may not be properly cured when pressed into substrates. In this way, the drilling quality may be very poor due to the insufficient strength of the resin itself, and there may be a lot of drilling pollution or serious tearing of the resin on the…
Today, we will introduce three special routing techniques for PCB. The following will explain the routing of PCB LAYOUT from three aspects: right-angle routing, differential routing, and serpentine routing: 1.Right-angle routing (three aspects) The impact of right-angle routing on signals is mainly reflected in three aspects: first, the corner can be equivalent to the capacitive…
