Inspection Conditions of IPC620 Standard

-
This standard lists objective, acceptance, and unfavorable conditions for different grades of products, and concession acceptance is also included. During the inspection, the inspector does not have to choose the level of product acceptance for assembly. This standard will provide the inspector with the level of product acceptance, the conditions are as follows: 
1. Objective: This state is close to perfect. This is an ideal situation and cannot be achieved. It is not necessary to ensure that the assembly requirements of this level are met.
Inspection Conditions of IPC620 Standard
2. Acceptance: The conditions need not be perfect, but the product must maintain the integrity and stability of the assembly in the working environment.
3. Concession acceptance: The condition of concession acceptance is not to affect the composition, installation, function, or stability of the product. Conditions such as materials, design, operators, or machines do not meet acceptable standards or are defective products. Concession acceptance should establish a tracking system in process control. Concession acceptance refers to the loss of control in the process, such as abnormal changes, identification of bad tendencies, or others, the process must be analyzed. The analysis results can reduce the table and increase the output. The treatment accepted by concession means that it can be used without affecting the product. The process control method is the use of electronic welding or electronic assembly in the planning, realization, and evaluation of the manufacturing process. The principles and strategies are implemented. The tools and processes can be applied to the process control and performance requirements of special companies, operations, or final products. The manufacturer needs to evaluate the most recent process control or continuous improvement plan.
4. Bad: Bad is the acceptance condition that does not meet the standard, and the structure, installation, function, or stability of the assembly in the final use environment is defective. The manufacturer must deal with each defect and have documentation support.
5. Disposal: The definition of disposal is how to treat defective products. Treatment methods include, but are not limited to, rework, concession acceptance, scrap or repair. Customers should be notified of concession acceptance.
6. The meaning of product grade: If grade 1 is a defective product, grades 2 and 3 are defective products. If level 2 is a defective product, it means that level 3 is a defective product, which does not mean that the product of level 1 is a defective product unless otherwise required.
7. Unspecified status: The unspecified defective status or process control status can be considered acceptable unless it can be determined that this status affects the end user-defined product composition, installation, function, and reliability.

  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...
