8-Layer Electronics 3 Oz Copper Base Multilayer Rigid PCB Security Electronics PCB,
FR - 4 epoxy glass fiber cloth substrate, based on epoxy resin as binder, with electronic level glass fiber cloth as reinforcing material of substrate. Its bonding sheet and thin copper-clad r.p. panel and inner core is an important base material in production of multilayer printed circuit board,This kind of product is mainly used for double-sided PCB, dosage is very large. Epoxy glass fiber cloth substrate, the most widely used model for FR - 4, in recent years because of the electronic product installation technology and PCB technology development needs, appeared high Tg FR - 4 products.
Immersion Gold and the difference between gold-plated plate 1, immersion gold and gold-plated crystal structure is not the same as the thickness of gold for gold than gold-plated lot of gold will be gold-plated gold is more yellow, more satisfied customers. 2, immersion gold and gold-plated crystal structure is not the same, Shen Jin is easier than gold-plated welding, will not cause poor welding, causing customer complaints. Immersion gold plate of the stress more easily controlled, there is a bonding of products, more conducive to the processing of bonding. But also because of the gold than the gold-plated soft, so Shen Jin-board do not wear gold finger. 3, immersion gold plate only nickel gold pads, skin effect of the signal transmission is in the copper layer will not affect the signal. 4, immersion gold than gold-plated crystal structure is more compact, not easy to produce oxidation. 5, with the wiring more and more dense, line width, spacing has come to 3-4MIL. Gold is easy to produce gold short-circuit. Immersion gold plate only nickel gold on the pad, it will not produce gold short-circuit. 6, immersion gold plate only nickel gold on the pad, so the resistance of the line with the combination of copper layer is more solid. Engineering will not compensate for the spacing of the impact. 7, generally used for the relatively high requirements of the board, flatness is better, generally use immersion gold, immersion gold generally do not appear after the assembly of the black pad phenomenon. Immersion gold plate flatness and standby life as good as gold-plated plate
HDI PCB, High Frenquency PCB
Based on a variety of parameters, HF signals are reflected on circuit board, meaning that the impedance (dynamic resistance) varies with respect towards the sending component. To prevent such capacitive effects, all parameters must be exactly specified, and implemented with the highest amount of approach manage.
Vital for the impedances inhigh frequency printed circuit boardsare principally the conductor trace geometry, the layer buildup, along with the dielectric continuous (er) on the supplies applied.
For many applications, it is sufficient to use FR4 material with an appropriate layer buildup. In addition, we process high-frequency materials with improved dielectric properties. These have a very low loss factor, a low dielectric constant, and are primarily temperature and frequency independent.
Additional favourable properties are high glass transition temperature, an excellent thermal durability, and very low hydrophilic rate.
We use (among others) Rogers or PTFE materials (for example, Teflon from DuPont) for impedance controlled high frequency circuit boards. Sandwich buildups for material combinations are also possible.
Our HDI PCB are ideal for many applicaitons, like communication industry, medical equipments, consumer electronics and automobile industry. We supply high-precision, high-density, double-sided and multilayer HDI PCB for mobile phones, computers, LED, etc.
