Essentials of FPC Design and Use
FPC not only has electrical functions, but also the mechanism must be balanced by overall consideration and effective design. ◇ Shape: First, the basic route must be designed, and then the shape of the FPC must be designed. The main reason for adopting FPC is nothing more than the desire...Read more -
The composition and operation of light painting film
I. terminology Light painting resolution: refers to how many points can be placed in one inch length; unit: PDI Optical density: refers to the amount of silver particles reduced in the emulsion film, that is, the ability to block light, the unit is “D”, the formula: D=lg (incident lig...Read more -
Introduction to the operation process of PCB light painting (CAM)
(1) Check the user’s files The files brought by the user must be routinely checked first: 1. Check whether the disk file is intact; 2. Check whether the file contains a virus. If there is a virus, you must first kill the virus; 3. If it is a Gerber file, check for D code table or D code inside. (...Read more -
What is a high Tg PCB board and the advantages of using high Tg PCB
When the temperature of a high Tg printed board rises to a certain area, the substrate will change from “glass state” to “rubber state”, and the temperature at this time is called the glass transition temperature (Tg) of the board. In other words, Tg is the highest temper...Read more -
The role of FPC flexible circuit board solder mask
In the circuit board production, the green oil bridge is also called the solder mask bridge and the solder mask dam. It is a “isolation band” made by the circuit board factory to prevent the short circuit of the pins of SMD components. If you want to control the FPC soft board (FPC fl...Read more -

Power equipment Switching regulator, DC/AC converter, SW regulator, etc. 3. Communication electronic equipment The hig...Read more -
The difference between aluminum substrate and glass fiber board
The difference and application of aluminum substrate and glass fiber board 1. Fiberglass board (FR4, single-sided, double-sided, multilayer PCB circuit board, impedance board, blind buried via board), suitable for computers, mobile phones and other electronic digital products. There are many ways...Read more -
Factors of poor tin on PCB and prevention plan
The circuit board will show poor tinning during SMT production. Generally, poor tinning is related to the cleanliness of the bare PCB surface. If there is no dirt, there will be basically no bad tinning. Second, tinning When the flux itself is bad, the temperature and so on. So what are the main ...Read more -
What are the advantages, applications and types of aluminum substrates
Aluminum base plate (metal base heat sink (including aluminum base plate, copper base plate, iron base plate)) is a low-alloyed Al-Mg-Si series high plastic alloy plate, which has good thermal conductivity, electrical insulation performance and mechanical processing performance. Compared with the...Read more -
The difference between leaded process and lead-free process of pcb
PCBA and SMT processing generally have two processes, one is a lead-free process and the other is a leaded process. Everyone knows that lead is harmful to humans. Therefore, the lead-free process meets the requirements of environmental protection, which is a general trend and an inevitable choice...Read more -
Differences in characteristics between FPC and PCB
In fact, FPC is not only a flexible circuit board, but it is also an important design method of integrated circuit structure. This structure can be combined with other electronic product designs to build a variety of different applications. Therefore, from this point on Look, FPC and hard board a...Read more -
