SMT贴片的点胶压力和胶量大小如何控制

SMT贴片点胶量的大小控制,根据工作经验,胶点直径的大小应为产品间距的一半,这样就可以保证有充足的胶水来粘结组件又避免胶水过多,点胶量多少由时间长短来决定,实际中应根据生产情况(室温、胶水的粘性等)选择点胶时间。
SMT patch dispensing amount size control, according to work experience, the size of the dispensing point diameter should be half of the product spacing, so as to ensure that there is sufficient glue to bond the component and avoid excessive glue, the amount of dispensing by the length of time to determine, in fact, should be based on the production situation (room temperature, glue viscosity, etc。) to choose the dispensing time。

SMT贴片点胶压力选择,点胶设备给针管胶枪提供一定压力以保证胶水供应,压力大小决定供胶量和胶水流出速度。压力太大易造成胶水溢出、胶量过多;压力太小则会出现点胶断续现象和漏点,从而导致产品缺陷。应根据胶水性质、工作环境温度来选择压力,环境温度高会使胶水粘度变小、流动性变好,这时需调低压力值,反之亦然。
SMT patch dispensing pressure selection, dispensing equipment to the needle gun to provide a certain pressure to ensure the supply of glue, pressure size determines the amount of glue supply and glue outflow speed. Too much pressure can easily cause glue overflow, too much glue, too little pressure will appear intermittent dispensing phenomenon and leakage point, resulting in product defects. Should be based on the nature of glue, working environment temperature to choose pressure, high ambient temperature will make the glue viscosity less, liquidity become smaller, then need to lower the pressure value, and vice versa.

SMT贴片点胶针头大小选择,在工作实际中,针头内径大小应为点胶胶点直径的二分之一左右,点胶过程中,应根据产品大小来选取点胶针头,大小相差悬殊的产品要选取不同针头,这样既可以保证胶点质量,又可以提高生产效率。
SMT patch dispensing needle size selection, in the actual work, the needle diameter should be about one-half of the diameter of dispensing point, dispensing process, should be based on the size of the product to choose dispensing needles, the size of the product to choose different needles, so that can not only ensure the quality of the glue point, but also improve production efficiency。
