Analysis of 01005 process in pcba processing and the reasons for the high cost of mounting
Good afternoon everyone, today I will share the 01005 process in pcba processing and the reasons for the high mounting cost. In pcba processing, 01005 is not only a problem of high precision, its processing price is also much more expensive than other specifications. Why is the placement cost of 01005 so expensive in smt processing?

The editor would like to tell everyone about a customer case. This customer is engaged in medical equipment products. Previously, the traditional component products used were also biased towards stability. However, he was relatively cautious about 01005 specification components.


Later, due to product upgrades and iterations, the accuracy and volume of this medical surgical robot have been optimized and improved. The 01005 specification must be used this time. In the quotation stage, customers expect to find pcba processing suppliers based on the target price of 0603. Later, after a round of inquiry, it was found that no one was willing to take orders at a loss, and finally was forced to raise his target price.

In general, 01005 in pcba processing is also used in the design of high precision and high value-added products, because the process of using 01005 components is relatively difficult, the packaging accuracy is high, and the process is complex, not only the processing cost is high, but the price itself It's not cheap either. In addition, there are several other items that will cause the overall product price to be high.


1. The pin spacing of the PCB:01005 original is very dense, which leads to improved PCB pad processing accuracy and more complex process requirements.


2. Solder paste: relatively high quality solder paste is required to control the solder climbing rate and soldering quality.


3. Reinforced mesh: Due to the problem of pin spacing, the process window is very narrow and the stability is relatively poor. There will be great requirements on the opening and material of the steel mesh.


4. Nitrogen: In order to ensure the welding effect, 01005 will generally use a nitrogen reflow oven for welding, whi

ch has higher requirements for equipment and will increase equipment expenditure.


For 01005, this product is mainly miniaturized and high-tech. Therefore, when setting 01005 process parameters, smt patch processing plants must strictly use SPI, AOI, X-ray and other testing equipment to optimize process parameters and assist processing.
The above is the reason why the electronic editor analyzes the 01005 process and the high mounting cost in pcba processing. If you have any other questions, please contact us to discuss and exchange, thank you.
