Half hole pcb The walls of the PTH holes on the PCB are plated with Half-hole formed by smooth and complete metal forming.The Half hole process on the edge of the board is already a mature process in PCBSKY PCB manufacturing processing. How to control the quality of the product after forming the Half-hole on the edge of the board. For example, the copper spurs of the hole wall and the residue have always been a problem in the processing. This type of board has a row of half hole in the PCB, which is characterized by a relatively small aperture, mostly used on the carrier board, as a daughter board of the motherboard, through the half-hole and the motherboard and components The feet are welded together. Therefore, if there are copper thorns remaining in these half-hole, the soldering of the plug-in manufacturers will result in inaccurate solder joints and weak soldering, which will cause a bridge short circuit between the two pins. Half hole pcb has a minimum processi...

After the double-sided PI board copper-clad board material is used in the double-sided circuit, a protective film is added on both sides to form a circuit board having a double-layer conductor. The Structure of the Double-layer FPC When the circuit of the circuit is too complicated, the single-layer fpc cannot be wired or copper foil is needed for ground shielding, it is necessary to select a double-layer fpc or even a multi-layer fpc. The most typical difference between a multi-layer fpc and a single-layer fpc is the addition of a via structure to join the layers of copper foil. The first processing technique of general substrate + transparent rubber + copper foil is to make via holes. First drill holes in the substrate and copper foil, after plating, a certain thickness of copper is plated, and the via holes are completed. The subsequent production process is almost the same as that of a single layer. Double-panel structure: Both sides of the double-sided panel have pads, whic...

Custom blind and buried vias fabrication  from professional and experienced pcb board supplier at low cost. First of all, we start with traditional multi-layer boards. The structure of a standard multi-layer circuit board is a process including an inner layer line and an outer layer line, followed by drilling, and metallization in the hole to achieve the internal connection function of each layer line. However, due to the increase in line density, the way parts are packaged is constantly updated. In order to allow for a wider board area, more high-performance parts can be placed. In addition to the thinner line width, the aperture is also reduced from 1 mm in the DIP jack to 0.6 mm in SMD, and further reduced to 0.4 mm or less. However, the surface area is still occupied, so that there are buried holes and blind holes. The Buried Holes and Blind Holes are Defined as Follows Blind Vias: A blind via is a type of via that connects the inner trace of the PCB to the trace of ...

The PCB on the computer consists of a motherboard, a hard disk, a memory module, a graphics card, and the like. The plane of the computer motherboard is a PCB (printed circuit board), generally four or six layers. Relatively speaking, in order to save costs, the low-end motherboards are mostly four-layer boards: the main signal layer, the ground layer, the power layer, and the sub-signal layer, while the six-layer board adds the auxiliary power layer and the middle signal layer. Therefore, the six-layer PCB The motherboard is more resistant to electromagnetic interference and the motherboard is more stable. You won't find electronics PCBs today only in computers - although laptops, smartphones, desktops and tablets certainly can't function without quality printed circuit boards, and printed circuit boards for computers make up a large part of the industry. Instead, you'll find machines containing printed circuit boards almost everywhere you look. Your television, wireless ...

PCB processing belongs to the OEM customer's OEM products. Different customers order different products, and there are few shared products. On the other hand, some customers may specify the use of a manufacturer's substrate for quality considerations. Ink and so on, in order to achieve its quality and cost control requirements, so PCB processing prices are changeable. What are the factors that affect the price of PCB processing? Basically consists of the following factors: First, the materials used in the PCB are different. Taking ordinary double-panel as an example, the sheets generally have FR-4, CEM-3, etc., the thickness ranges from 0.6mm to 3.0mm, and the thickness of copper varies from 1oz to 3oz. The price varies greatly from specification to specification; In terms of ink, there is also a price difference between ordinary thermosetting ink and photosensitive green ink, so the difference in materials causes price diversity. Second, the PCB uses different production proc...

Electroplating can be divided into hard gold and soft gold. Hard gold electroplating is an alloy, so its hardness is relatively hard. It is suitable for use in places requiring force and friction. It is generally used as the edge contact point of PCB (commonly known as golden finger). Soft gold, On the other hand, is commonly used to connect aluminum wires On the COB (Chip On Board) or On the touch surface of mobile phone keys, and more recently, it is widely used On both sides of BGA boards. The distinction of hard gold and soft gold, it is the component of this layer of gold that goes up finally plating, when gold-plating can choose electroplate pure gold or alloy, because the hardness of pure gold is softer, so also call "soft gold". Function of auxiliary components in   hard gold plating PCB   plating solution: Boric acid ACTS: as a buffer, which can maintain a relatively balanced PH value of hard gold-plated PCB plating solution with a concentration of 35~55g/l; N...
