Production Flow
Our advantage
Material Technology
Our Production
General Production
1.Our (TG170)FR4:
high quality materials, excellent heat resistance, won't distort break in high temperature, no foaming, no burning, good
performance in electrical charge, impact resistance, humidity-resistance

2.Our FR4
good performance in electrical charge, impact resistance, humidity-resistance

3.Our CEM

4.Our Rogers
Good performance in high frequency

5.Our Aluminum
Excellent heat dispersion
1.General FR4
High heat work

2.General CEM
Expand and deform in damp conditions
We have automatic production line. The automatic production line improves the precision and efficiency of PCB producing,it makes
surface brighter, cleaner and more smooth, and it helps reduce the cost.
Artificial production line
Blind/buried via board, High Density Interconnect(1+1,N+1)
Application of HDI technology reducing the thickness and the volume of PCB boards, increasing the density of 3-D wiring design.
Difficult manufacturer, high cost
Good performance in reliability and stability of signal sending and receiving
High cost
Surface Technics
1.IMG:smooth surface, good adhesion, no oxidation under long using plating(thick gold:1-50U"):good wear-resistance
3.HASL:better price, not easy oxidation, easy to welding, smooth surface
4.HAL: better price, not easy oxidation, easy to welding
1.IMG:high price
2.Gold plating(thick gold):high price
3.HAL:surface is not flat, not suitable for BAG packaging
Copper Via/Surface(20-25UM,0.5-60Z)
Laser holing: Min 0.1MM, Mechanical holing: Min 0.2MM
Hard to reach 0.1MM
Multilayer board(4-20 L),BGA(CPU)
BGA:high density, high performance, multifunctional, increase thermal reliability, good performance in electroheat property, MIN
width/space: 3/3MIL

Multilayer board:strong microporous, high reliability
Difficult manufacturer,high cost
To assure quality, avoid wasting after installing and scraping, save cost, save the time of rework
