Low price and reliable configuration used to be the most popular marketing slogan of Internet mobile phone manufacturers, but now more and more manufacturers are trying to remove the “low price” label and transition to the high-end market. Beginning from 2017, the major Internet mobile phone manufacturers began to collectively “yell”. First, the Huawei Honor …
Properties and uses of PCB copper plating and nickel plating
Properties and uses of copper plating: The copper plating layer has a beautiful rose color, is soft in nature, rich in ductility, easy to polish, and has good thermal and electrical conductivity. However, it is susceptible to oxidation in the air and quickly loses its luster, making it unsuitable as a “surface” layer for protective-decorative …
Analysis of the advantages of laser marking in the PCB industry
Laser marking is a very advanced marking technology. Through focused laser engraving technology, the characters and patterns that need to be marked are engraved on the surface of the object. Compared with traditional printing technology, laser marking has the characteristics of good quality, high consistency, strong abrasion resistance, high efficiency, cost savings and safety and …
Do routing bit have all tungsten steel and welded classifications like drill bit? What about the unit price and the difference in quality?
Theoretically, both methods are feasible, but because the routing bit is subject to a large lateral force, if the welding method is used, the quality control must be quite good. Each method is different, and the unit price is also very different. Traditional tool factories have emphasized on one-piece construction. Without joints, better mechanical stability …
Maintenance of printed circuit board plating production line
There are two main types of electroplating equipment used in the production of printed circuit boards. One is a horizontal electroplating line and the other is a vertical electroplating line. These two different structures of electroplating equipment are mainly different in the transportation method of circuit boards. The structure of the conveying plate equipment used …
PCB circuit board standards
The shape should be as close to a square as possible. It is recommended to use 2 × 2, 3 × 3,…; The width of the PCB circuit board is less than or equal to 260mm (SIEMENS line) or less than or equal to 300mm (FUJI line); if automatic dispensing is required, the width of …
3D sensing diffuses from consumer electronics to industry applications
3D sensing technology is spreading from consumer electronics to commercial applications. It is expected that it will be introduced into the automotive field to drive the development of self-driving and unmanned vehicles. The 3D sensor link includes algorithms, lasers, lenses and modules. The optical lens factory ignited yesterday. Today, laser-related stocks have strengthened. The industry …
PCB surface treatment
The most basic purpose of PCB surface treatment is to ensure good solderability or electrical performance. Since copper in nature tends to exist in the form of oxides in the air, it is unlikely to remain as copper for a long time, so other treatments of copper are needed. 1. Hot air leveling (spray tin) …
PCB raw materials prices continue to rise, breaking the industry’s original pattern
There are many types of raw materials required for PCB production, mainly materials such as copper clad laminate (CCL), prepreg (PP), copper foil, copper ball, gold salt, ink, dry film and so on. Generally speaking, in the cost structure of PCB, about 37% of copper clad laminates, 13% of prepregs, 8% of gold salt, and …
5G Smart Mobile Era Drives 3D Glass Market Demand Growth
At this stage, the development of mainland smartphones has entered a relatively mature stage, and the upgrade space for hardware configuration is gradually reduced, and it is becoming more and more difficult to make major innovations in functionality. Mainland mobile phone manufacturers have begun to continuously improve the personalization of mobile phone appearance, materials and …
