Jan 30th, 2007 IntroducingSilver Through HoleTechnology What is Silver Through Hole? To conduct both sides of circuits, Silver Paste replaced traditional copper as the conductive material through holes. 銀膠，代替了傳統的銅箔，作為通孔中的導體導通兩面線路。 Unlike traditional PTH, advance Silver-through-hole deploy precise silk screen printing instead of heavy metal electro-plating process. 不同于傳統的PTH，先進的銀膠貫孔采用精確的絲印工序而非重金屬電鍍工序。 Advantages of using STH 使用STH的優勢 Cost Saving (20%-25%) 節省成本(20%-25%) Less Expensive Laminate 板料價格更便宜 Environmental Friendly 100% Lead-free 環保，100%無鉛 O.S.P. finish ensure flat pads for SMT OSP表面處理為SMT保証平整的焊盤 Compatible to all soldering processes 適用于所有焊接過程 Wide application for consumer appliances 廣泛應用于消費器具中。 Production Process制程 Comparison betweenSTH and PTHPCB STH 與PTHPCB對照 Cross Sections for STH PTH 切片對照 Laminates application Processing Differences Less expensive laminate板料更便宜 Green Process綠色制程 Save higher cost from Electro-plating節省了電鍍所需的高成本 Much more savings for Mass Production 大量生產中可節約更多成本 Can save cost up to 20% to 25%. 成本節約率可達20%，25%。 Mature application in similar end-products 成熟應用于同類終端產品 Cost Saving 節約成本 Environment Friendly 環保 Ease of modification 易于修正 Can support Lead-free Soldering 能支持無鉛焊 Issue of Material Circuit Solder Mask CNC Drilling Punching Carbon Print Over Coat Mark STH E-Testing O.S.P FQC Package Outgoing End-products Application 終端產品應用 Computer Peripherals (DVD-ROM)電腦周邊 Mobile Communications移動通信 Medical Electronics醫學電子 RF Remote Controls無線遙控 Hand-held Electronic devices手持式電子器件 Security Access Controls安全及訪問控制 Air-condition Console空調控制板 Automobile Dashboard汽車儀表板 Other Consumer Electronic Appliances其它消費電子器具 STH - Silver Through HolePTH - Plating Through Hole Silver Through Hole Plating through hole PTH STH Laminate OK適用 OK適用 FR-4 OK適用 OK適用 CEM-3 N/A不適用 OK適用 CEM-1 N/A不適用 OK適用 FR-1 Thermal adhesive Ink UV Ink Legend Printing文字印刷 PTH STH Process Heavy Metal重金屬 Green Product綠色產
