PCB Technical - How to develop PCBA labor and materials

1. The development trend of PCBA labor and materials

1. The PCBA package of labor and materials requires the foundry to have the ability to analyze and solve design problems.

The updating speed of electronic products is getting faster and faster, and the life cycle of products is getting shorter and shorter. In many cases, it is no longer possible to leave too much laboratory verification process for the product side; the product will be put into the production process after the basic functions are available. At this time, suppliers who are contracting labor and materials are faced with the situation of dealing with R&D and design issues in the production process. For example, the parameters of some components are improperly selected; the design of some PCB circuits has defects. To cope with this situation, the foundry that is contracting labor and materials must make such preparations in terms of production process and technical service capabilities.

2. The management and control of PCBA labor and materials components has gradually changed from model control to function control.

In the process of contracting labor and materials, it is inevitable that sometimes we encounter alternative materials. Previously, it was more to choose replaceable components, cost down, or be an emergency replacement. However, a more innovative approach is to replace some of the functions with updated versions to achieve a functional leap and product quality improvement. For example: the original LM2596 switching power supply solution, because the product has relatively loose requirements for power supply ripple, it can be replaced with the LM2576 with a lower switching frequency. Starting from the customer's product characteristics and use environment, rather than deadlocking parameters to choose alternatives. Realize the improvement of component management and control from model parameters to functional goals. create value for customers!

3. PCBA contracting labor and materials has changed from simply contracting labor and materials to providing upgrade and replacement programs.

The competition of products is becoming increasingly fierce, and the upgrades are getting faster and faster. More and more major customers also require foundries to be able to gradually provide some development work while completing the work in the production process of contract labor and materials. Since the foundry produces and tested products for a long time, it has a relatively comprehensive grasp of the electrical performance of the entire equipment; if it is not a particularly large change, only the size, power consumption, stability, user experience and cost considerations, it can completely pass the foundry To achieve product upgrading and transformation. In this way, the foundry must prepare and accumulate in PCB production, power supply design, and stability design to be able to calmly respond to the needs of customers.

2. Precautions for PCBA labor and materials

1. Line design

For a PCBA, a good circuit design is the basis for success. The circuit design according to the actual needs of the product is the most basic. However, some engineers may forget to consider the actual processing difficulty in the process of designing the circuit. The processing cost of the same function board due to the different processing difficulty is definitely different, and it is not conducive to the electronic processing circuit board. In the processing process, it will also encounter some problems that hinder the processing efficiency and actual use performance.

2. Material selection

For PCBA packaging materials, materials are one of the key factors to ensure quality, such as the material of the circuit board, the selection of electronic components and so on. If you want to produce a high-quality board, the choice of materials is very important. The process and materials of the board can be directly requested. The procurement of components can be given standards and price ranges, and the supply of important components can also be specified directly. Commercial brands. In the quotation of labor and materials, there is often a situation where the quotation is higher than the psychological price of the entrusted processing party. This actually requires targeted communication between the R&D enterprise and the PCBA processing plant. The quality of high-quality components is difficult to buy at the price of inferior products. Arrived. If you need to control costs, you also need to communicate with the purchasing staff of the processing plant. How to reduce costs while ensuring the quality of the product plan is also a technical task.
