Silicon Technology Co., Ltd. Hong Kong

Silicon Technology Co., Ltd. is a professional manufacturer of PCBs and SMTs. Our factory was founded in 1986 in Hong Kong, and mainly produces single or double-side PCBs, carbon oil boards, silver carbon through hole PCBs, multilayer PCBs, flexible PCBs and electroless gold plating PCBs. Our factory was moved to Buji Town, Shenzhen, China in 1991. As a result of rapid development, our company set up a factory in Shenzhen City in 1995. With a total area of 18,000m2 and a production area of 12,000m2, our monthly production capacity for single side and double & multilayer PCBs is 35,000m2 and 20,000m2 respectively. Besides, our factory was ISO9002 and ISO14001 certified by UL and SGS third party laboratories. We have been devoted to enhancing product quality and after-sales service in order to satisfy customers' needs by continually upgrading our quality management and production technology. Our Printed Circuit Board Process Capabilities are as follow: -Base material: CEM-1, CEM-3 FR4, High TG, Teflon, and AL base -Finished Board Area (Max.): 600mm*700mm (24000mil*27500mil) -Base board thickness: 0.4mm-4.0mm (15.75mil-157.5mil) +/- 0.1mm (4mil) -No. of Layers: Single, double and multilayer up to 16 layers -Copper thickness: 0.5-4.0oz (17.5um-0.14mm) -Finished board exterior tolerance: (1) CNC: 0.15mm (6mil); (2) DIE: 0.10mm (4mil) -Min line width and spacing: 0.1mm (4mil) with line tolerance < +/- 20% -Min drill Hole: 0.25mm (10mil) -Min DIE Hole: 0.9mm (35mil) -Hole tolerance: (1) PTH: +/-0.075mm (3mil); (2) NPTH:+/-0.05mm (2mil) -Copper thickness in hole: 18-25um (0.71-0.99mil) -Min. space between SMT paste: 0.1mm (4mil) -Surface Finish: Immersion gold, HASL (Pb or Pb free), Plate gold, OSP, and Blue pastern -Solder mask thickness: 10-30um (0.4-1.2mil) -Solder mask rigidity: >5H -Medium constant: e= 2.1-10.0 -Characteristic impedance: 60 ohm+/-10% -Thermal stress: 288 deg, 10 sec, and 3 times -Finished board warp: < 0.7% -PCB Applications: Communications, Auto electronics, Apparatus meters, GPS, Computers, LEDs, and Gold Fingers In order to broaden our product category, we make great effort in the R&D for the development of PCBA to produce a complete range of product. A blood glucose meter is one of our promotional products. With the comparison data analysis of current famous brand blood glucose meter, our products have been entitled as an accurate and reliable products. On the other hand, we also cooperate with a mini notebook manufacturer, acting as a distributor. With a strong philosophy of quality management, our aim is to supply good quality products to our customers. No matter it is a semi product such as PCB or a complete product such as blood glucose meter and mini notebook computer, we will follow our quality management philosophy to maintain and improve our product quality to satisfy the market need.
