PCB multilayer fabrication - lay-up and bond
The outer layers of our multilayer consist of sheets of glass cloth pre-impregnated with uncured epoxy resin (prepreg) and a thin copper foil.he multilayer pcb is mainly used in professional electronic equipment,such computers and military equipment, especially in the case of the overload of weight and volume.The mltilayer pcb is also very useful in high-speed circuit. The mltilayer pcb can provide more space for the conductor pattern and power. Gold Phoenix PCB Co.,Ltd., a branch of Gold Phoenix Tech,Multilayer PCB Prototyping

Multilayer Registration Control

Prediction: Layer-to-Layer Alignment
One primary characteristic is layer to layer alignment. In addition to our MultiLine tooling systems, we have purchased and implemented the use of the PerfecTest system to fine tune our process and achieve highly accurate scale factor predictions for a variety of material types and core thicknesses. which provides us with the ability to produce a wide range of multi-layer PCBs with embedded resistors, capcitors, connector assemblies, blind, buried and plugged vias available. We also have the ability to produce multi-layer PCBs with metal cores and metal backing. Please complete our printed circuit board enquiry form for more information.

multilayer pcb means the layer count >2 layer , it has circuit line on two side of the boards ,to use the two side circuit layer we have to use a conductor to connector to two layer circuits . plated through hole (PTH) is to make copper on hole wall and these copper can connect the circuit line on two side. the double side pcb is important and widely use in electronics industry.We can produce a wide range and many type of double side pcb , the base material we use from regular like FR-4 to Rogers all are purchased from UL approved supplier(see more infomation about our different pcbs.).

Overview

The primary intent of fabricating a multilayer printed circuit board is to provide one more degree of freedom in the selection of suitable routing paths for complex and./or noise sensitive electronic circuits. Such considerations as layer to layer impedance aside, what we are really trying to do is stack two or more circuits on top of one another and establish a reliable set of predetermined interconnections between them. There are a number of well established techniques that are routinely used by the printed circuit industry to accomplish this. However, they all suffer from their reliance on a large number of chemical processes (as many as 15) to condition the substrate, activate the through-holes and electrolyticly plate copper between the adjacent layers. The following method reduces this dependence on "wet chemistry" to a single acid copper electroplating bath and relies on a small set of easily mastered processes to eliminate the need for much of the complexity normally encountered in multilayer board prototyping. is specialized in Flex PCB & Rigid PCB prototyping, PCB manufacturing, PCB assembling and stencil in China.UK manufacturer of printed circuit boards. From our site in Leicester we support a wide product range of high technology PCBs for the military, medical, aerospace, telecoms and other industries, Our speciality is the manufacture of prototype or small to medium size batches of PCBs. With over 40 years experience in the PCB industry we will work with you to meet your requirement in technology, delivery and cost.

We manufacture a vast range of pcb's with our expertise covering simple single sided boards through to high count flexi-rigid multilayer boards. We have a large experience handling many different types of materials from ceramic to PTFE and everything in between.

The multilayer pcb is made up by two or more pcbs which are stacked together with reliable predefined mutual connection between them. There are at least three conductive layers in one multilayer pcb with two layers outside and the one layer synthetized in the insulation board. Due to the complex manufacturing process and lower production , the cost of multilayer pcb is relatively higher.

The lay-up operator has already placed a copper foil and 2 sheets of prepreg on the heavy steel baseplate. Now he places the pre-treated core carefully over the alignment pins. Then he adds 2 more sheets of prepreg, another copper foil and an aluminium press plate
