PCB Tech - Why the cost of SMT patch conversion is too high

The reason why the customer chooses the processing factory to process the SMT patch is because the quantity is large, and the price will be relatively cheaper. These are all considered when the customer chooses. I just want to find an SMT chip processing factory, but many will encounter it. The manufacturer is not willing to take this order, it is not cost-effective, unless it is a large number of orders. In the case of a small quantity, the so-called loss is large, and it is also a loss of time. Because at the same time, the production efficiency of SMT patch processing is higher, and it will not waste time in the morning after the production. Do the preliminary work.

Is the SMT patch conversion cost too high because it is a small batch?

The following smt patch processing will tell why there are other costs for small batch proofing.

1. In small batches, SMT patch conversion costs are too high. The investment of manpower and material resources cannot make up for the cost. For example, if you play 100 tablets, it is really not worth the depreciation cost of such expensive equipment. Unless the customer has long-term cooperation with these factories. Without considering the cost. Because before SMT chip processing, regardless of whether large-volume SMT chip processing or small-batch SMT chip processing, the preliminary work that needs to be done is the same, such as: SMT chip processing machine programming, PCB positioning, and starting the first piece Confirm this category.

2. There are also some SMT patch processing plants that are reluctant to take small orders because the processing costs are different. Some manufacturers will choose to match their own users, and some SMT patch processing plants will specialize in serving large customers, because The quantity is large and the orders are relatively stable. Relatively speaking, the profit of a single product will not be too high. If you grab a certain number of large customers, you don't have to worry about receiving scattered orders and their respective factors;

3. As long as anyone who has learned SMT patch processing knows, the cost of SMT patch processing is generally calculated by the number of components, one patch (resistor 0603, 0805, capacitor, diode) counts as one point, one transistor Calculate 1.5 points, the four pins of IC are counted as one point, and count all the patch points on the PCB board. Processing fee = points * unit price of 1 point (the processing fee includes: red glue, solder paste, washing water and other auxiliary materials) If the number of SMT patch processing points is too few, the lower consumption of 500 according to the SMT patch processing factory Meta calculation.

Large-volume processing will be more welcomed by processing factories. If you calculate based on the above content, then the cost of small batches, or start-up costs in some places, is too small, the labor cost is not enough, and the machine is worn out, which is basically a waste. time. This is the reason why small batches of SMT patch processing and proofing will be charged with engineering fees.
