Kester 952S助焊剂是一款专门为电路板组装波峰焊而研发的无卤素,不含松香的**酸型助焊剂。非常低的固态物含量(2%)及活性剂系统特性使得焊后几乎没有助焊剂残留,电路板在波峰焊后,表面干燥且外观干净,没有残留影响电子测试,节省了清洗的费用。 Kester952S展现了改良的焊接性能,较小化减少桥接(短路)和过分焊接的缺陷。此助焊剂不导电,无腐蚀性,符合Bellcore TR-TSY-000078规范较严格的要求。952S适合应用于汽车电子,计算机,电信产品等可靠度要求高的产品。焊后板子上的表面绝缘阻抗**一般的**酸型水溶性助焊剂。 按照J-STD-004标准, Kester952S被定义为L型助焊剂。通过了对于高可靠性产品的表面绝缘阻抗的要求。 Kester 952-S is a halide-free, non-rosin organic fluxdesignedforwave soldering of conventional and surface mountcircuitboardassemblies. The extremely low solids content (2.0%) andnatureofthe activator system results in practically no residue leftontheassembly after soldering. Boards are dry and cosmeticallycleanasthey exit the wave solder machine. There are noresiduestointerfere with electrical testing, and the expense ofcleaningiseliminated. Kester 952-S exhibits improved solderingperformancetominimize solder bridges (shorts) during reworkoperations.Thisnon-corrosive and non-conductive flux meetsthestrictestrequirements of Bellcore GR-78 specifications. Thisfluxissuitable for solar, automotive, computer,telecommunicationsandother applications where reliabilityconsiderations arecritical.The surface insulation resistance onsoldered boards ishigher thanthat provided by typicalorganicwater-solublefluxes.
