F118P / F118BRoHS
Ultra-Low Residue Lead-Free No-Clean Flux
Features
- 采用专门树脂研制的第四代新型低固体焊剂,成膜无色透明、光泽良好,不发白发雾。
- 焊后残余物极少且无色透明,不粘污 PCB;成膜不发粘、绝缘电阻高、无腐蚀性,焊后完全免清洗,允许在线测试。
- F118B 为消光型,消光性能与可焊性俱佳,特别适宜高密集焊点装联、高密集双面板焊接。
- F118E 为高活性型,配低成本 SnCu 型焊料时可得近似有铅 Sn63 的焊接质量。
- F118P 为超低残留无铅型,焊接后板面与未使用助焊剂几乎没有差异;对低成本 SnCu0.7 波峰焊与普通 Sn63 有铅波峰焊效果近似。
- 对各种焊料适应面广,焊接烟雾小,与各型预涂焊剂工艺匹配性极佳。
- 适用范围:波峰焊、浸焊等群焊工艺,手工焊、元器件与接插件引线搪锡,以及 PCB 预涂。
- 涂布方式:浸涂、刷涂、喷涂、鼓泡。推荐群焊流程:焊前准备 → 喷涂 F118E/P/B → 过波峰 → 风冷 PCB → 检验修焊。
- 储存:避光,置阴凉通风干燥处,有效期一年。与市面流行焊剂可直接切换,无需处理。

Related Grades
F116 / F116R / F116T
Resin-Type No-Clean Flux
Medium-solids resin no-clean flux. Pale film, high gloss, very little fume - ideal for lines without extraction.
F101 / F101B / F101R
Water-Soluble Flux
High activity, fast wetting - even heavily oxidised terminations tin in one pass. Residue washes off with plain water.
F114 / F114B / F114C
General-Purpose Resin Flux
For hand iron and wave soldering; runs on low-cost S502/602 solder to cut manufacturing cost.
F117 / F117B / F119
Pre-Coating Flux
PCB pre-coating for oxidation protection and solderability. Very high activity; F119 is the low-solids grade for dense and multilayer boards.
F105 / F105A
High-Activity Aluminium Soldering Flux
Developed for aluminium-to-copper replacement in electrical work. Joins Al+Al, Al+Cu, Al+Fe/stainless, Al+Ni, Al+Zn and their alloys.
F107 / F107T / F107R
Stainless Steel Flux
Water-soluble flux for tinning stainless pins on connectors; even heavily oxidised areas tin in one pass, residue rinses off with water.
