Reasons for the difference in connector plating quality

-
In order to ensure the quality of the gold-plated layer, connector manufacturers often repeatedly study the problems that may occur in the quality of gold-plating technology. Regarding the color of the gold-plated layer of the connector of the connector is different from the normal gold-plated color, and the gold-plated layer in the same product is significantly different The problems have been explained, and the basic mountains can be summarized into the following 4 reasons:
​Reasons for the difference in connector plating quality
The effect of impurities in gold plating raw materials. When the gold plating process is performed, the impurities brought in by the plating solution's chemical materials will exceed the gold plating solution's use standard and will soon affect the color and brightness of the gold layer. The phenomenon of darkening and flowering of the cash layer or the interference of metal impurities will cause the effective range of the current density to be narrowed, which will show that the low end of the current density is not bright or the high end is not bright and the low end is not coated.
The current density of the gold plating is too large. When the total area of the plating parts of the gold plating process is incorrectly calculated, the value is larger than the actual surface area, and the amount of gold plating current is excessive. Or when the vibration electroplating gold is used, the amplitude is too small. In this way, the gold plating of some of the plated parts in the plating bath is rough, and the gold layer will be visually red.
The aging of the gold plating solution, during production, due to the use of some gold plating solutions for too long, excessive accumulation of impurities in the plating solution will inevitably cause the abnormal color of the gold layer of gold plating products.
The content of the alloy in the hard gold plating layer changes because of the needs of some gold plating processes. In order to improve the hardness and wear resistance of the connector, a hard gold plating process is generally used. Among them, gold-cobalt alloys and gold-nickel alloys are used more. When the content of cobalt and nickel in the plating solution changes, the color of the gold plating layer changes, so this will result in the same batch of products provided to customers. When the cash layer is not the same color.
When producing and designing connectors, because of different product requirements, there will also be different plating processes, especially when some customer-customized connector products often require relatively high electrical performance requirements, so connector manufacturers will Different gold plating processes are used according to different needs.

  SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). It is controlled and communicated by the "Truck and Bus Electrical & Electronics Committee" (Track & Bus Electrical & Electronics Committee). Developed and written by the Track & Bus Control and Communications Network Subcommittee. J1939 has become a recognized industry standard and choice for commercial vehicle diagnostics and data communication heavy, off-highway, truck, bus, ship propulsion, power generation, industrial pumping, construction, and material handling machinery. J1939 is a high-level protocol network (CAN) based on Controller Area. It is widely used by the diesel engine industry to provide diagnostic data such as vehicle engine speed, temperature, oil temperature, exhaust emissions, and other customizable options. J1939 connectors are divided into black and green rubber cores, but do you know the difference between t...

Benefits of overmolded connectors and wiring harnesses?

What is overmolding? In short, overmolding is an injection molding process in which two or more materials are used to combine a harness wire and a connector to form a single part, and the cable assembly is placed in a mold. In this process, the first material substrate will be covered by other materials. The overmolding process requires the use of insert molding (single injection) or multiple injection molding techniques to cover rigid plastic parts with TPU layers or other overmolding materials. So what are the benefits of the connector and harness overmolding process? Benefits of overmolding connectors and harnesses: 1. Increase the flexibility of the cable harness exit so that most of the movement between the cable harness and the connector occurs at the cable harness exit. 2. Provide abrasion resistance, impact resistance or impact resistance. 3. Fix the cable assembly by sealing the assembly in plastic. 4. Provide 360 degree strain relief and increase tension. 5. Cr...

​Cars are equipped with diagnostics tool or obd-ii ports

Modern cars have the capacity of a few computers, are tooled with software that contains millions of lines of programming code and produce gigabytes of data, but they are still different from connected cars. ​ A smart vehicle is able to optimize its performance to reduce fuel consumption, show the best path to follow taking into account current traffic and weather conditions, detect errors in the engine and collect information data to negotiate lower insurance rates. Most cars and light trucks are equipped with on-board diagnostics or an OBD II port that provides access to data from the engine control unit (ECU). To get the information you need to plug in an external device. The OBD-II specifications provide a standardized hardware interface - a female 16-pin (2x8) J1962 connector, so a single external device can be used for most car models. It also should have an Internet connection to transfer the collected data. OBD-II connects to the Internet, and generally needs to use th...
