In the process of pcab processing and production of PCBA assembly electronic products smt technology production workshop, how to manage the anti-static equipment, avoid the electrostatic damage in the process of pcba processing and production, and improve the quality of electronic products? The following anti-static requirements are introduced by the smt technical engineer of Shenzhen Shiyan smt SMT Factory.
1, smt technology workshop electrostatic workbench: by workbench, anti-static workbench pad, wrist strap connector and ground wire.
2, smt technology workshop anti static station pad on the wrist strap joints should be more than two, one for the use of smt technology operators, one for smt technicians or smt inspectors to use.
3. It is not allowed to pile up plastic boxes, rubber, cardboard, glass and other sundry objects which are easy to produce static electricity on the anti-static safety workbench. The drawing materials should be stored in an ESD bag.
4. Anti-static wrist strap for pcb factory smt technology workshop. Operators who directly contact electrostatic sensitive components must wear the anti-static wrist strap, which is in good contact with human skin.
5. Anti-static containers, parts fixing bags, turnover boxes in smt technology workshop, PCB circuit board loading and unloading racks in pcba processing and production site should have electrostatic protection function. Metal containers and ordinary containers are prohibited. All containers must be grounded.
6, smt technology workshop anti-static work clothes. The operators entering the electrostatic work area and the personnel touching the SMD components must wear antistatic work clothes, especially in the dry environment with the relative humidity less than 50% (such as autumn and winter). All the antistatic work clothes of the smt technology workshop in the processing plant must meet the relevant national standards.
7. All personnel entering the working area of smt technology workshop of pcb board manufacturers must wear anti-static work shoes and electrostatic cap. Personnel wearing ordinary shoes should use conductive LACES, anti-static shoe cover or heel belt.
8. The conveyor belt and transmission shaft used in the smt process workshop production line of the SMT processing plant should be equipped with anti-static grounding brush and telegraph pole.
9. Ion wind electrostatic eliminator can be used on the surface of conveyor belt.
10. Assembly fixtures, test fixtures, welding tools and various instruments used in the production of pcba processing site in smt technology workshop should be equipped with good grounding wire.
11, smt technology workshop production pcba processing site should be installed at the entrance of anti-static test bed. , everyone entering the pcba production site should be subjected to the antistatic test and must pass the test before entering the smt technology shop.
The above is the basic anti-static equipment of PCBA processing and assembly of electronic products in chip processing plant. After several years of development, many smt production workshops have been newly added.
1) The smt technology workshop of pcb board manufacturer needs to install real-time monitoring equipment, so as to monitor the static electricity of human body, equipment and table mat at any time, so as to find problems in time and solve the first problem.
2) Install an anti-static monitoring system in the smt technology workshop of chip processing plant to visually display and analyze the occurrence of static electricity, so as to facilitate the ESD protection management of PCBA processing smt technology workshop.
