一、前言印制电路的基材—复铜箔层压板的铜箔清洗擦板工序,目前已从手工操作发展为刷板机擦洗。刷板机的主要作用是用机械方法清洁板面,除去铜箔表面的氧化层,机械沾污,钻孔边缘残留的毛刺,并对铜箔表面进行‘粗化’,使贴感光膜增强附着力。刷板机所用的刷辊是起这一作用的主要部件。因此,刷辊的好坏,直接影响擦洗复铜箔层压板的质量。SBJ-3型刷板机原来用的是铜丝刷辊。铜丝刷辊擦洗铜箔表面,仅起抛光作用,表面粗化效果较差,并且使用寿命短,铜丝易产生卷曲和掉毛现象。国外刷板机常用刷辊是含磨料的尼龙丝刷辊和毛毡型刷辊,后者是用合成纤维制成,用粘胶剂使磨料
First, the foreword Printed circuit substrate - copper foil laminate copper foil cleaning wipe process, has been developed from manual operation for the brush plate machine scrub. The main function of the brush plate machine is to clean the plate surface mechanically to remove the oxide layer on the surface of the copper foil, mechanical stains and burrs left on the edge of the hole, and roughen the surface of the copper foil to enhance the adhesion of the photosensitive film Efforts. The brush roller used in the brush plate machine is the main part that plays a role. Therefore, the brush roller is good or bad, directly affect the scrub complex copper foil laminate quality. SBJ-3 brush plate machine was originally used copper wire brush roller. Copper wire brush scrub copper foil surface, only from the polishing effect, surface roughening effect is poor, and short service life, easy to produce copper wire curling and hair loss phenomenon. Foreign brush plate brush machine is commonly used with abrasive nylon wire brush roller and felt brush roller, the latter is made of synthetic fibers, with the adhesive to make abrasive
