Board-to-board connector manufacturing steps
2019-06-16 Board to board connector
Manufacturing steps of board-to-board connectors: The rapid development of technology in recent years has greatly promoted the manufacture of electronic products. As a vital component in electronic products, connectors have become more and more concerned by users. Connector manufacturers around the world have set off a madness in technological innovation. At this moment when the connector market is unpredictable, the rapid development of the market has accelerated the technological innovation of connectors, and the design level and processing methods of connectors have also been greatly improved. In today's era, although there are many types of electronic connectors, the manufacturing process is basically the same.

1. stamping
The board-to-board connector is generally manufactured from a stamped pin. Through a large high-speed press, the connector (pin) is stamped from a thin metal strip. One end of the large rolled metal strip is fed into the front end of the press and the other end is worn. The hydraulic workbench of the punching machine is wrapped around the take-up reel, and the metal strip is pulled out by the take-up reel and rolled out to punch out the finished product.

2. plating
After the connector pin is stamped, it should be sent to the plating section. At this stage, the connector's electronic contact surface will be plated with various metal coatings. A type of problem similar to the stamping phase, such as twisting, chipping or deformation of the pins, also occurs during the process of feeding the punched pins into the plating equipment, and quality defects are easily detected.

3. injection molding
However, for most machine vision system suppliers, many of the quality defects that occur during the plating process are also the “forbidden zone” of the inspection system. Electronic connector manufacturers want the inspection system to detect various inconsistencies such as small scratches and pinholes on the connector pin plating surface. Although these defects are easily identifiable for other products, such as aluminum can bottom covers or other relatively flat surfaces, visual inspection systems are difficult to obtain due to the irregular and angular surface design of most electronic connectors. It is enough to identify the images needed for these subtle defects.

4. assembly
New machine vision systems are becoming more widely used due to the ever-increasing demands of manufacturers to increase production efficiency and product quality and reduce production costs. As various vision systems become more prevalent, people are becoming more familiar with the characteristics of such detection systems and have learned to consider the detectability of product quality when designing new products. If you want a baseline to detect the "actual position", you should consider the visibility of this baseline in the connector design.
