High Tg represents: a high heat resistance. Usually high Tg of 130 degrees or more plates, excellent high Tg is generally greater than 170 degrees, moderate Tg greater than about 150 degrees, PCB boards normally Tg≥170 ℃, called high Tg PCB. With the rapid development of the electronics industry, especially in the computer as the representative of electronic products toward high performance, high multi-layered development requires a higher heat resistance as an important guarantee of PCB substrate material. The emergence and development of SMT, CMT, represented by high-density mounting technology, the PCB in a small aperture, fine lines, thin side, increasingly inseparable from the high heat resistant substrate support.

    Tg of the substrate is increased, PCB thermal resistance, moisture resistance, chemical resistance, stability and other characteristics will improve and improve. TG higher the value, the better the sheet temperature resistance, especially in the lead-free process, the high Tg applications more.

    General FR-4 differs from high Tg FR-4 is: 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.

Thus, in the technological development of high-tech needs of today we are becoming increasingly large, with a very good role, but also to give businesses more profitable and improve efficiency.

Role: According to engineering design requirements for interconnection between PCB layers,

           Turned and finished plug-in installed, drilled to conform Find holes.

working principle:

      A, mechanical drilling: drilling rig by the CNC control computer system

           Made machine to move, press the Enter computer information

           Create customer desired hole location.

      B, laser laser, etc.

Key equipment: mechanical rig (main brands are Hitachi, Schmoll, etc.) laser drilling rig

Specification:

Blind hole with blue soldermask TG140 printed circuit board FR-4 material is a fire code rating, represents a material specification is meant a resin material through the combustion state must be self-extinguishing, it is not a material name, but a material grade. So now FR-4 grade material is typically used in circuit boards, there are many species, but most are based on the so-called four-function (Tera-Function) plus epoxy filler (Filler) and glass fiber made composite materials.

Competitive Advantage:
1) With UL,ROHS,ISO,IPC
2).Lead time:3-10 working days
3)Competitive price best quality
4).Rich 20 years experience in High Tg Multilayer PCB .
What Information customer need to provide for quotation ?
1. PCB Gerber files ,protel,powerpcb,Autocad,etc.
2. BOM list for PCB assembly.
3. Send us your sample PCB or PCBA.
4. OEM is acceptable.
