Double Layers PCB consist of two copper layer on a rigid base material, the two copper layers are not connected . Double sided pcb’s with plated through holes have two copper layers that can be connected by a copper plated hole , solder resist and idents can also be added. Double sides PCB are a step above single sided in their complexity. Double Sided PCBs require plated through holes to provide better anchoring for soldered components and front to back electrical continuity. Double Sided circuit boards were the gateway to higher technology applications.We offer a wide range of Double Sided PTH PCB board which is known for its excellent performance and user friendliness for you .This type of pcb can be used for both through hole and surface mount components.
Specification:
4-layer Multiple Gold PCB with Minimum Hole Size Of 0.2mm Industrial Camera Board
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
