PCB layout is PCB design.PCB design needs to be realized by computer aided design. The commonly used design software in the industry is cadence Allegro, pads, Altium designer. Conventional PCB design includes several steps, such as database building, network adjustment table, layout, wiring, file output, etc., but the conventional PCB design process is far from…
1. Multilayer flexible PCB raw materials (1) It is divided into glued materials and glue less materials. The copper on the material is divided into copper and calendared copper, and the material without rubber and copper is better in flexibility and folding. (2) Thickness of material: PI+ copper thickness 2. Multilayer flexible PCB cover film…
A Multilayer Flexible Printed Circuit Board (FPCB) is a type of circuit board that is flexible and consists of multiple layers of flexible substrate material. The basic structure of a multilayer flexible PCB typically includes the following components: Substrate Material: The base material of a flexible PCB is usually made of a flexible polymer, such…
The gold-plated circuit board is divided into electroplated hard gold (gold alloy) and water gold (pure gold) process. The composition of hard gold and soft gold bath is basically the same, but there are some trace elements of metal nickel or cobalt or iron in the hard gold tank. 1. Purpose and effect of gold-plated…
Ultra-thick copper multilayer pcb is an integrated connector with strong and weak electric connection function. The manufacturing technology of ultra-thick copper multilayer pcb sheet over 0.41 mm is studied. The superimposition of single-side copper clad sheet and 1.0 mm black copper sheet and epoxy sheet and single-side copper clad sheet and the bonding of non-flowing…
1. Double sided flexible PCB upper line screen printing First, we need to select materials, baking pretreatment, in order to prevent the contraction of the material deformation to the process after the trouble. 2. The diameter of blanking carbon hole for double sided flexible PCB The blanking carbon hole is generally 0. 8 to 1.…

3. Technical level of PCB products All kinds of commercialized PCB products in the world can be produced in mainland China and cannot be produced at the same level. The technical performance of the same kind of PCB products varies greatly. High frequency electrical property and dimension stability (CET) of PCB are closely related to…
Today, the PCB industry has released a technology that can produce high density multi-layer flexible printed circuit boards by screen printing, which is also a leading technology in the PCB industry. With this screen printing technology, the multi-layer high density flexible printed circuit board embedded in components can be printed and processed completely. Width (L)…
At present, China's manufacturing industry (including PCB industry) has gradually entered the era of intellectualization, but also brought new opportunities and challenges to PCB enterprises. So in the era of manufacturing intellectualization, what exactly should PCB enterprises do? At the beginning of the speech, the industry leaders said frankly that the current industry environment is…
Goldfinger PCB: insert one end of PCB board into connector slot, use connector socket as the outlet of external connection of PCB board, make the pad or copper skin contact with the socket foot of corresponding position to achieve the purpose of conduction, and plating nickel and gold on the pad or copper skin of…
The drilling condition of printed circuit boards for communication is too bad. The main performances are: more resin dust in the hole, rough hole wall, serious hole burr, hole burr, inner copper foil nail head, uneven length of tear section in glass fiber area, which will cause certain quality hidden danger to chemical copper. Brush…
Layering and color changes in the gold-plated layer of a PCB (Printed Circuit Board) can be indicative of various issues or changes that may occur during the PCB manufacturing process or over time. Here are some reasons for layering and color changes in the gold-plated layer of a PCB: Oxidation: Gold is known for its…
