UV protective coating adhesive for circuit board is a single component UV curing acrylate adhesive with high bonding strength and fast surface drying under ultraviolet irradiation. It is suitable for automatic operation and greatly improves production efficiency. The main curing methods of circuit board coating protective adhesive are: UV curing, double curing of light-moisture, double [...]
With the number of mobile devices growing faster than the global population, a serious problem must be addressed. What do we do when all consumer electronics and other products are no longer in use? It is clear that stacking devices at landfills have serious environmental and economic implications. Researchers at the university of Illinois are [...]
As the circuit board industry grows, overall manufacturers' military and aerospace sales are also growing, according to IPC analysts. While budgets for the U.S. military and aerospace programs are shrinking, PCBS tend to do more business among manufacturers than in other vertical markets. Printed circuit boards for these applications must meet stringent quality and performance [...]

Flexible circuit board Soft circuit board is also called flexible circuit board, flexible circuit board. Short for flexible board or FPC, it is made of flexible insulation substrate. Is relative to the ordinary hard resin circuit board, the flexible circuit board has the advantages of high wiring density, light weight, thin thickness, less wiring space [...]
How to repair circuit board without drawing? 1. "have a plan" To thoroughly understand the principles of some typical circuits, by heart. The drawings are dead, the ideas in the head are alive, can be compared, can reason, can draw inferences from one example to another, and can all be understood. For example, the switching [...]
Solvent cleaning technology for PCB board Solvent cleaning is mainly the use of solvent solubility to remove pollutants. Using solvent cleaning, because of its rapid volatilization, strong dissolution ability, so the equipment requirements are simple. According to the choice of cleaning agent, can be divided into flammable cleaning agent and incombustible cleaning agent, the former [...]
Circuit board of the issues that need to be from the brazing technology, brazing adopts the liquidus temperature is lower than the base solidus temperature of solder metal materials, components and solder will be heated to melt solder, using liquid solder wetting parent metal, filling and joint clearance with parent metal dissolution and diffusion, and [...]
PCB circuit boards, also called printed circuit boards, printed circuit board, is an important electronic components, electronic components to support the body, is the carrier of electronic electrical connection, with insulating board base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening [...]
4. Other auxiliary materials 1) pure adhesive: this adhesive film is a kind of thermosetting acrylic ester adhesive film, which is composed of protective paper/release film and a layer of adhesive, mainly used for lamination board, soft and hard bonding board, and fr-4 / steel sheet reinforcing board to play an adhesive role. 2) electromagnetic [...]
