无铅锡膏印刷滚动性及落锡性
印刷滚动性及落锡性好,对低至0.3㎜间距的焊盘也能完成精美的印刷,连续印刷时,其粘性变化极少,钢网上的可操作寿命长,超过12小时仍不会变干,仍保持良好的印刷效果;印刷后数小时仍保持原来的形状,基本无塌落,贴片元件不会产生偏移;      The printing roll and fall tin, to as low as 0.3 mm spacing of the pads can also complete the fine print, continuous printing, viscosity change little, the steel net operation life is long, more than 12 hours will not dry, still maintain a good printing effect; printing a few hours after the original remains shape, no collapse, patch element does not generate offset;   具有极佳的焊接性能,可在不同部位表现出适当的润湿性;可适应不同档次焊接设备的要求,无需在充氮环境下完成焊接,在较宽的回流焊炉温范围内仍可表现良好的焊接性能。用“升温-保温式”或“逐步升温式”两类炉温设定方式均可使用;焊接后残留物极少,颜色很浅且具有较大的绝缘阻抗,不会腐蚀PCB,可达到免洗的要求;
  With excellent welding performance, can be in different parts of the show proper wetting; can be adapted to different grades of welding equipment requirements, without the need for nitrogen environment to complete welding, over a wide temperature range reflow can exhibit good welding performance. " Heat - insulation type " or " gradually warming type " two kinds of temperature setting mode can be used; after welding the residues are less, the color is very shallow and has good insulation resistance, corrosion will not be PCB, can reach the requirement of disposable;
