1. Introduction

△ TUOPU THC11 flux is a flux with high solid content (12% solid content) and higher activity. It can be used in foaming, spraying and other forms.

△ The resin active system has excellent wettability on the surface of bare copper and solder layer.

△ The welding of multi-layer boards with metallized small holes will show excellent penetration performance.

2. Features and advantages

△ Some special activators added to THC11 flux are used to reduce the surface tension between the solder mask and the solder, which greatly reduces the generation of solder balls.

△ The heat-stable activator in the high-solid no-clean flux reduces the incidence of continuous soldering defects in wave soldering and selective soldering.
