Production Flow

Our advantage
Material Technology	Our Production	General Production
Regular/Special	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 no-burr 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
Factory	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
Impedance	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 2.gold 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
Test	To assure quality, avoid wasting after installing and scraping, save cost, save the time of rework	Careless
