PCBA Tech - PCBA labor and materials and no materials

PCB board manufacturers are in the 21st century. Many new electronic products and technologies will be updated rapidly. As the most important core component of electronic products, the PCB processing industry has received great attention from major companies in the industry. The quality of the PCB processing industry, Delivery time and cost will directly affect the delivery quality, delivery time and cost of the entire product.

At present, well-known PCBA foundry companies in the world include Foxconn, Flextronics, BYD and other well-known companies. They have maintained cooperative relations with many internationally renowned electronic product developers. Their successful cases have led to the processing methods of modern electronic manufacturing services. In summary, there are two main types: processing with supplied materials and contracting labor and materials. At present, more and more companies in major industries choose the PCBA package of labor and materials mode. Why do more and more companies choose PCBA for labor and materials? So what problems will these two modes encounter in actual operation? The following will be briefly discussed and analyzed by the Shenzhen smt patch processing plant.

1. Concept description

1. PCBA labor and materials is actually a kind of processing method, including looking for all the processing processes of PCBA processing, such as PCB circuit board production, raw material procurement, smt processing, PCBA testing, and finished product assembly. To put it simply, the purchaser places the order to the supplier, and then the supplier delivers the finished PCBA to the customer, and the supplier handles all the intermediate processes.

2. The difference between PCBA labor and materials and PCBA labor and materials is that the materials on the BOM are all provided by the purchaser, and the supplier is only responsible for production, which is equivalent to processing with supplied materials.

Two, a brief analysis of the two methods

(1) PCBA contract labor does not include materials. The advantage is that the quality and brand of each material are relatively controllable; the disadvantage is that it needs to face many component suppliers, which is not easy to control as a whole, and procurement corruption issues are prone to occur. Staff input is also high. The threat is: once a large number of suppliers have supplier problems, they will be involved in all sets of supply problems.

(2) PCBA contract labor and materials, the advantage is: integrating supply chain channels, holding better bargaining power, can reduce the number of suppliers, avoid the passive situation of PCB board manufacturers chasing materials everywhere, and save a lot of other trivial matters Time, such as: signing contract terms, order follow-up, payment processing, ERP operations, etc.; disadvantages: there may be raw material quality and raw material brand control issues; the threat is: untimely payment may lead to overall material supply problems; but At the same time, there is still an opportunity for PCBA contracting labor and materials, which is that the disguised financing (accounting period negotiation) has less personnel input, which saves labor costs. Large PCBA suppliers have large bargaining powers for raw materials and can simultaneously reduce costs.

Three, the current mainstream way

The choice of two paba processing modes, PCBA labor and materials and processing with supplied materials, has always been difficult for companies to choose, and everything will have two sides.

Combined with comprehensive analysis and evaluation, PCBA labor and materials can save customers time, cycle, inventory and other cost issues. Investment in outsourcing, logistics and personnel. At present, this method is increasingly becoming the first choice of system integrators and product manufacturers.

However, taking into account the confidentiality of some core integrated chips and some production burning procedures, the current more mainstream method is to use part of the labor and materials method, that is, the core chip is provided by the company, and the other PCBs and blocking containers Pieces and so on are provided by PCBA processing factory. At the same time, simple testing and burning are completed by the PCBA processing factory, and the responsible and core program burning and testing are still done in the enterprise factory.

Fourth, the potential derivative risks of PCBA labor and materials

In the process of PCBA contract labor and materials service, the audit of suppliers is very important, which almost determines the key to the success of the cooperation, and the key to whether the cost and product turnover can achieve the expected goals. It is undeniable that the market is indeed flooded with businesses that obtain excess profits by sacrificing customer quality and stealing raw materials, but after all, this is not sustainable development; therefore, suppliers who choose PCBA for labor and materials should be included in the strategy. The scope of cooperation of cooperative suppliers. Of course, the procurement corruption of such key suppliers in the import process also requires enterprises to pay close attention to.
