PCBA Tech - What are PCBA, PCA, and FPCA?

The difference between PCBA,PCA,and FPCA.

Many professionals in the field of non-PCBA processing cannot accurately distinguish these professional terms often used by practitioners in the electronics industry.

PCBA (Printed Circuit Board Assembly) refers to a substrate with a complete hardware structure formed by soldering electronic components to a PCB circuit board.Switch control,so as to achieve the design of product functions).

PCA is equivalent to PCBA,which is more often spoken by professionals in Hong Kong,Taiwan,Europe,and the United States.

The first letter F of FPCA means Flexible printed circuit board assembly, which refers to a hardware substrate formed by soldering electronic components to a flexible printed circuit (FPC, Flexible Printed Circuit).

What exactly are PCBA labor and materials?

1.Features

PCBA contracting labor and materials can reasonably and effectively save customers' time and labor costs.The whole process of production and manufacturing is controlled by professional suppliers,which avoids bargaining and waste of time in the procurement of various electronic materials,and can reasonably and effectively reduce inventory costs., Inspection time, personnel expenses,etc.

The quotations of PCBA labor and materials seem to be high, but in fact,PCBA processing plants can reduce business costs and allow companies to focus on their special areas, such as design, R&D, marketing, and after-sales service.

2.Potential risks

A very critical process in the PCB assembly contracting of labor and materials is to select excellent suppliers for processing.It is undeniable that there are indeed some merchants in the market who gain excess profits by sacrificing customer quality,stealing raw materials,etc,but a one-shot deal won't last long.Lepeng Technology believes that this type of approach is the bottom line for companies that are determined to grow and develop in the manufacturing industry. Therefore, the most important thing for auditing suppliers is to feel what they do, to behave in the world, and from the perspective of solving problems for customers. These aspects are better than equipment, factory scale, certificates, etc.

3.The trend of PCBA contracting labor and materials

Digital product manufacturing PCBA patch processing has developed for decades. The competition in the manufacturing industry has become saturated, and the average profit rate of the manufacturing industry is low and stable. In the market, there are countless suppliers who have no bottom line to fight prices, and these are often just for cost-sharing or the need for survival. Customers who are familiar with electronic manufacturing are very aware of the transparent quotations in the market, even if they include components, etc., so they can completely accept the package of labor and materials and only need to provide reasonable profits to the supplier.

FPCA SMT

The SMD process for fpcas can be performed on either medium or high speed mounters depending on the product characteristics, number of components and placement efficiency. SMD (Surface Mount Device) placement on FPCs is not much different from placement on PCBs, as each FPC carries an optical MARK mark for positioning. However, it should be noted that although the FPC is fixed on the carrier board, but its surface still can not be as flat as the PCB hard board, and the carrier board will certainly exist between the local gap. Therefore, during the placement process, it is necessary to accurately set parameters such as nozzle drop height, blowing pressure, and reduce the nozzle moving speed.

In addition, since FPC usually exists in the form of joint boards and the yield rate is relatively low, it is very common for the whole PNL (panel) to contain some defective PCS (parts). This requires the mounter to have a BAD MARK recognition function, otherwise the production efficiency will be greatly reduced in the case of producing such non-all-good boards.

With the intensification of PCBA market competition, the large and comprehensive operation mode is only suitable for medium and large companies. For small companies, what needs to be done is to focus on areas of expertise,such as market development. Subdivided markets and refined operations are the directions for the future development of small and medium sized enterprises.
