Technical Issues and Solutions
Missing Print: The solder cream is not printed on the area that is more than 25% larger than that of the PAD.
The mesh may be blocked, or part of the solder cream is adhered to the bottom of the steel mesh. In this case, the bottom of the steel mesh must be cleaned, and the stripping speed is decreased.
The steel mesh is short of solder cream, or the tin paste is not well distributed along the direction of width of the scraper. Under the circumstance, the solder cream should be added along the direction of width of the scraper.
The viscosity of the solder cream is too high, and the printing effect is not desirable. In this case, the tin paste supplier is requested to provide the solvent. Additionally, please select the proper viscosity of Sn42Bi58 low temperature lead free solder paste for LED.
