No clean flux 803 Introduction

No clean flux 803 is a low solid content no clean flux specially designed for the no cleaning process, which contains synthetic resin and a combination of activators. It has a low solid content. This flux is used for welding equipment such as single and double peaks, small tin furnaces, etc., for welding single and double sided boards, multi-layer boards.

No clean flux 803 Product Features

➤ After welding, the surface of the board is bright and even, and the welding points are full and bright.
➤ The residue after welding is fast and dry, uniform and consistent, and has a very high surface insulation impedance (S.I.R).
➤ The residue on the board is even and non-sticky, forming a uniform protective film on the PCB and solder joints, making it easy for the finished product to pass PIN-TEST testing.
➤ When PCBA products with high reliability requirements require full cleaning after welding, this product can meet the requirements.

No clean flux 803 Application

➤ When applying the spray process, be sure to keep the spray amount of PCB uniform to achieve good welding results. Reduce soldering defects.

➤The service life of soldering flux varies slightly due to process conditions. It is recommended to use compressed air spray that is degreased, dewatered and cooled to extend the service life of the flux. When the flux is not in working condition, it should be kept in a sealed container as much as possible to avoid solvent evaporation. When it is necessary to replace expired flux, the flux container should be thoroughly cleaned before replacing with a new flux.

➤Pre heating after application of flux can maximize the advantages of 803 no clean flux. It is recommended that the preheating temperature should reach 80-90 ℃ on the PCB welding surface after preheating. The recommended operating speed is 1.0-1.5 meters per minute.
