Motor Control Board Battery Protection Circuit In Green Soldermask With Blind Hole Electronic Board

Motor Control Board Battery Protection Circuit In Green Soldermask With Blind Hole Electronic Board

Quick detail:

Specification:

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.

Specification:

Blind holes from one side of the board to see the hole, but the other side did not get through. Blind hole only to realize is conductively connected to several specific layer.

Only one of the top or bottom layer visible, another layer that is invisible, that the blind hole is drilled from the surface, but do not drill through all the layers. Blind holes may be as long from 1-2 or from 4-3 (advantage: 1,2 3,4 conduction does not affect the alignment); and vias throughout 1,2,3,4 layer of irrelevant the alignment layer influential, but the higher cost of a blind hole, we need to laser drilling machine. Blind orifice is applied to one or more communication with the inner surface layer, the hole in the side of the side of the board, and then through to the interior of the board so far; simply put, is a blind hole surface can only see one side, the other side in the plate yard. General application in four or more than four PCB board.

General FR-4 differs from high Tg FR-4: in the hot state, especially in the heat after moisture absorption, the mechanical strength of the material, dimensional stability, adhesion, water absorption, thermal decomposition, differences in thermal expansion and other various conditions, high Tg products significantly better than conventional PCB substrate material.
