Heming Technology -IPC "cleaning guide" Standard Unit President, R & D production and sales of electronic manufacturing cleaning agents, water-based cleaning equipment, national high-tech enterprise flux, solder paste. ??? 20 years to concentrate on business, electronic manufacturing experience, we explore different areas in a recent application. Cleaning the SMT process, PCBA cleaning, steel mesh, copper mesh and plastic mesh cleaning, SMT equipment maintenance, reflow, wave soldering and maintenance, and many other applications to power electronics and assembly cleaning. I. Introduction??? W1000 is a neutral water-based cleaning agent can quickly and effectively remove SMT stencil printing uncured red plastic residues, and pre-reflow solder paste residues, achieve very good cleaning effect . For 3-5mm SMT thick plastic and copper network, together with the co-Ming ultrasonic stencil cleaning machines, can easily solve the thick red plastic mesh cleaning problems. Second, the advantages of water-based cleaning agent 1. generally difficult to clean the thick red plastic mesh, it has a very good cleaning effect. 2. The red plastic with a strong solubility can shorten cleaning time, reduce cleaning costs and improve cleaning efficiency. Third, the application??? W1000 neutral water-based cleaning agent can be used in ultrasonic and spray cleaning process off-line, is used to remove SMT stencil printing solder paste residues and red plastic, various types of aid flux residues also have some solubility. Specific application results are listed below list. Cleaning Range: stencils and misprinted board cleaning uncured red plastic SMT stencil printing ★★★★★ uncured red plastic SMT printing copper mesh ★★★★★ uncured red plastic SMT printed plastic net ★★★★★? paste (before reflow) SMT solder paste printing stencil ★★★★★ (pre-reflow) misprints board (PCB) ★★★★★ ★★★★★: strongly recommended; best; ★★ ★: Recommended; ★: possible; O: not recommended. Fourth, the cleaning process ultrasonic cleaning process specific process: Dosing Feeding → → → ultrasonic cleaning ultrasonic rinse / spray rinse / dry → Cutting
