SMT chip processing of must know clearly here:
The first: the combined standard electrostatic discharge control program development. Including the design, establishment, implementation and maintenance must be electrostatic discharge control program. According to the historical experience of some military organization and business organization, provide guidance for electrostatic discharge sensitive period for treatment and protection.
Second: welding technology assessment handbook. Contains 45 articles on various aspects of welding technology, the content involves the ordinary welding, welding materials, welding and manual welding, soldering, batch reflow soldering, welding and gas phase infrared welding.
Third: the second half of Aqueous Cleaning Handbook welding. Including all aspects of semi aqueous cleaning, including chemical, equipment, process, production residues, process control and environmental and safety considerations.
Fourth: through hole welding point evaluation desk reference manual. Components, the hole wall and the welding surface coverage and described in detail in accordance with the standard requirements for, in addition to including computer generated graphics in 3D. Covers the fillet, contact angle, tin, vertical filling, pad cover as well as a number of welding point defects.
Fifth: template design guide. Design and manufacturing for the solder paste and surface mount adhesive coating template provides guidelines on I template design and application of surface mount technology was also discussed, and introduced with hole or flip chip components? Combined technology, including printing, printing and double stage type template design.
Sixth: Aqueous Cleaning Handbook after welding. Describe the manufacturing residues, aqueous cleaning agent types and properties, aqueous cleaning process, equipment and process, quality control, environmental control and safety of the employees and the determination of cleanliness and determination of the cost.
