With the development of the electronics industry, in particular the demand for rapid development of computer, electronic communication equipment, and household appliances, double-sided and multi-layer printed circuit board is great.
The PCB hole metal from the complex requirements of electrical conductivity, weldability, coating toughness and economy, the non-copper perfectly. Further other non-metallic materials (such as plastic, ceramic, etc.), electroless copper plating applications also very wide. In the future, the aspect of non-metallic materials, metal, copper plating the amount of about 90%. Currently, the LSI chip production, instead of aluminum interconnects using electroless copper wiring width of less than 90nm.
Electroless copper plating solution from stability can be divided into low and high stability of electroless copper electroless copper stability; from the deposition rate to points, can be divided into low speed and high speed copper plating rate. The former deposition rate is generally 2μm / h ~ 4μm / h; the latter is generally 10μm / h.
High speed copper plating is generally used for semi-additive method or full-additive method directly thick steel plating, has been the rapid development of high temperature and low-temperature high-speed craft.
In recent years there has been differential copper plating method, namely through the pore walls of the PCB copper layer thickness is about the complex chemistry of the copper layer on the copper layer thickness finished school three times to 5 times, not only reduces the metallic copper consumption, but also reduce the cost, called the fourth milestone in the history of copper plating.
Electroless copper plating solution generally consists of copper, complexing agents, reducing and stabilizing agent.

Vacuum coating vendors would vacuum coating equipment vacuum coating when replace electroplating is the biggest challenge facing the diffraction properties of film layer preparation. Because the vacuum coating is done in a vacuum film preparation, film deposition is parallel to the evaporation source, workpiece must be in the face of the evaporation source, use widgets more structure, vertical plane of the... deposition rate even in preferable magnetron sputtering diffraction also is parallel to the plane of the evaporation source only one 5 of the deposition rate. More than this, the vacuum coating for the surface more artifacts or circular workpiece, cannot be used for complex artifacts, which are greatly limited the application of vacuum coating to replace water electroplating, slow down the pace of the application of vacuum coating of green environmental protection. For fasteners, the six sides need coating workpieces, usually using vacuum coating clips, hang card, will make the workpiece surface coating not blind spots, acid and alkali and water vapor and oxygen erosion, forming erosion point will aggravate corrosion of fasteners and so cannot use vacuum coating commonly used clamp fixed artifacts, hang card, and so on.
In order to solve this problem, this project designs a unique basket cage type workpiece, such as screw bolt fasteners in a workpiece in the basket, basket inside the cloth has a flip flap, when the basket cage workpiece cycloid reciprocating motion, fasteners, form the new face of sedimentary source side, multi-layer flip, so as to realize uniform coating of every side of fasteners.

What to buy vacuum coating machine equipment should pay attention to?

What to buy vacuum coating machine equipment should pay attention to?

Large investment funds items, we will be very careful when buying, it would be ready before the purchase of the required detailed understanding of the work done, a vacuum coating machines are not cheap, with the fast development of vacuum coating industry, for the film to be coated product requirements are also gradually increase, for the use of materials is also gradually expand the scope, and that the vacuum coating machine to keep the product in terms of rhythm with a certain challenge. Now we have to introduce a few precautions to purchase vacuum coating machine.

First, the configuration of the vacuum system: quality and price will always be proportional, regardless of what kind of technology the purchase of machinery and equipment, evaporation or, ions or, magnetron sputtering, or, the same function of the machine, with different configuration, the price is definitely a difference. In general, the use of materials on behalf configured well, the natural life will be longer, the efficiency will be higher, film better.

Second, the vacuum coating machine housing: If the surface, basically difficult to see is good or bad, not only from the surface gives the visual effect to distinguish the case basically every vacuum equipment manufacturers can be processed out. For the case should focus on sealing, welding is very important, if you buy back the equipment found to have leakage problems that customers will be very headache, even indirectly, some inexplicable problems, causes leak occur often because processing not good. Therefore, customers choose to buy vacuum coating machine / coating equipment when we must focus on processing power.

Third, the core technology: the different processes used in the core is not the same, unified call evaporation source, but it is a target head or electronic guns. If you do not have good evaporation source, basically not try to complete the stable quality of the coating. Good evaporation source is needed after years of constantly improve and perfect coating of data and then come out, do not understand the process of evaporation source manufacturers difficult to do. If what manufacturers say that their equipment does not include the process, some do not buy it.

Fourth, field trips, samples proofing: Before you buy or coating equipment vacuum coating machine, take samples to coating, check the film coating system is not able to reach their own requirements, its technical service and after-sales service is not perfect, combined with the above mentioned consulting Consulting more points, the last shop around
