Several standard problems needing attention in SMT SMT processing

Several normative issues that need to be paid attention to in SMT SMT processing need to be understood here:

Joint specification for electrostatic discharge control program development. Includes the planning, setup, implementation, and maintenance of esd control procedures. Provide guidance for electrostatic discharge treatment and protection during sensitive periods based on the historical experience of certain military and commercial arrangements.

Second: welding skill evaluation manual. Contains articles on all aspects of welding skills covering general welding, welding materials, manual welding, batch welding, wave welding, reflow welding, gas phase welding, and infrared welding.

Third: after welding half water cleaning manual. Covers all aspects of semi-hydrogenic cleaning, including chemical, manufacturing residues, equipment, processes, process control, and environmental and safety considerations.

Fourth: Through hole welding point evaluation table reference manual. Detailed descriptions of components, hole walls, and cover-ups of welded surfaces as required by the specification, in addition to computer-generated 3D graphics. It covers tin filling, contact Angle, tin dipping, straight filling, pad covering and numerous weld spot defects.

Fifth: template planning guide. Supply guidelines for planning and making templates for solder paste and surface mount binder also discuss template planning using surface mount skills and introduce?

Sixth: water cleaning manual after welding. Describe manufacturing residues, types and properties of hydrogenic cleaners, hydrogenic cleaning processes, equipment and processes, quality control, environmental control, and worker safety and cleanliness measurements and their costs.
