The purpose of PCB vacuum packaging is to prevent dust and moisture.      24. The quality policy is: **Quality control, implementation of the system, to provide the quality of customer needs; full participation, timely processing, to achieve the goal of zero defects.      25. The three no policies of quality are: do not accept ** products, do not manufacture ** products, and do not flow out ** products.      26. QC seven techniques in the fishbone check the cause of 4M1H are (Chinese): people, machines, materials, methods, environment.      27. The composition of the solder paste contains: metal powder, solution, flux, anti-drop agent, active agent; by weight, metal powder accounts for 85-92%, by volume metal powder accounts for 50%; where the main components of metal powder for tin and lead, the ratio of 63/37, the melting point of 183 ℃.      28. Solder paste must be taken out of the refrigerator when using back to temperature, the purpose is: let the refrigerated temperature of the paste back to room temperature, in order to facilitate printing. If not return to temperature in the PCBA into the Reflow easy to produce ** for tin beads.      29. the machine's file supply mode are: ready mode, priority exchange mode, exchange mode and quick connect mode.      30. SMT PCB positioning methods are: vacuum positioning, mechanical hole positioning, bilateral clamping positioning and board edge positioning.         31. The resistor with a silkscreen (symbol) of 272 has a resistance value of 2700Ω, and the resistor with a resistance value of 4.8MΩ has a symbol (silkscreen) of 485.      32. The silkscreen on the BGA body contains information such as manufacturer, manufacturer's part number, specification, and Datecode/(Lot No).      33. The pitch of 208pin QFP is 0.5mm.      34. the seven QC practices, the fishbone diagram emphasizes the search for cause-and-effect relationships;      35. CPK refers to the current process capability under actual conditions;      36. Flux starts to evaporate in the constant temperature zone for chemical cleaning act

Ultra-high speed modular bonder cm602
Ultra-high speed modular bonder cm602 Ultra-high speed modular bonder cm602 CM402 created the myth of SMT sales, in just over 2 years time global sales of more than 3000 units. With its flexible, combination of stable production and ** cost-effective loved by the majority of customers, widely used in notebooks, MP4, cell phones, digital products, automotive electronics and other ** industry. With the continuous improvement of product processing technology, the placement machine also put forward higher requirements. In order to meet the requirements of industry development and better serve our customers, Panasonic Industrial Co., Ltd. has improved and developed the CM602, a new generation of mounter**, based on the original CM402.   The CM602 not only uses the original CM402 modules, but also adds a new 12-nozzle high-speed head and direct-absorbing tray as needed, expanding the original 8-nozzle high-speed bonder head function, plus the 3-nozzle multifunctional head with pressure control function, making it as many as 10 different module combinations, truly modular, allowing customers to combine and match at will. The high speed version of CM602* reaches a high speed of CPH100,000, and the speed of a single bonder head reaches CPH25,000, which is unmatched by other equipment in the industry at present. New linear motors are adopted for both XY axes to provide strong power to CM602.    ● The motion arm beam and head adopt new design and material, which not only reduce the weight but also greatly strengthen the rigidity, making it more stable during the motion.    ● High-speed and low-vibration design has been adopted for the X Y axis movement.    ● The linear motor adopts a new cooling design scheme, which enables faster and more effective cooling than other equipment using linear motors in high-speed motion, ensuring efficient operation and increasing the life of the motor.    The 7 types of racks can be used for all kinds of ribbon packaging components from 8mm to 104mm, which is the most versatile and widely applicable equipment in the industry. The new 8 mm single rack has been added according to customer demand.    The design of the overall exchange cart and the overall exchange support pin can greatly improve the operation efficiency and the machine switching time.    While improving productivity, the software, hardware, and operation are all based on the proven design of the CM402, ensuring interchangeability with the CM402.
