the staff of the enterprise often turn a blind eye to many problems, or think that it is harmless, or think that it cannot be changed. there are also many managers who tend to turn a blind eye to intuitive information and focus only on numbers. as a result, it may slip through the cracks, ignore some key clues, and fail to truly understand the true state of the enterprise. as a customer, you should go to the supplier's site to understand its cost composition, production efficiency, quality control. as a supplier, we should go to the customer's site to understand its production process in order to better serve customers. as a peer, if you have the opportunity to visit other circuit board factories, it is also a very good opportunity to learn, compare and reference. enterprise operation is a big system, all links are closely related and affect each other. for production-oriented enterprises, through any details of the scene, you can know the micro. any big problem can be found at the, 1, pcb wire welding this method does not require any connectors, as long as the external connection point on the pcb printed board is welded directly with the components or other components outside the board. for example, the speaker in the radio, the battery box, etc. circuit board interconnection welding should pay attention to: (1) the welding pad of the welding wire should be as far as possible on the edge of the pcb printed board, and arranged according to a unified size to facilitate welding and maintenance. (2) in order to improve the mechanical strength of the wire connection and avoid pulling the solder pad or printed wire off due to the pull of the wire, drill holes near the solder joints on the pcb printed board, let the wire pass through the hole from the welded surface of the printed board, and then insert the solder pad hole from the component surface for welding. (3) arrange or bundle the wire neatly, and fix it with the board through the wire card or other fast
