SMT patch design, process and supply chain
Skills to complete patch program design SMT patch process inertial navigation and guidance
Many insiders are not very clear about how SMT patch programming for SMT patch processing is implemented on automatIC patch. For SMT wiring, programming is an important processing technology, which can effectively improve the processing of wiring processing. work efficiency. Here is a brief introduction to how to design the placement program on the placement machine.
1. Program editing
1. Call up the optimized program.
2 Make image PCB MARK and partial Mak
3. Make images of components that have not yet been imaged and register them in the image library.
4. Register unregistered components in the component library.
5. The multi tube vibrating feeder with unreasonable discharge shall be redistributed according to the length of the device body.
6. The placement accuracy can be improved by changing the multi pin, narrow spacing equipment and long socket with large contour into single polar.
2. Proofread
1. According to the component list in the SMT chip processing process file, check whether the component name, bit number, model and specification in each step of the program are correct, and correct the wrong part according to the process file.
2. Check whether the components on each feeder station of the mounter are consistent with the picking program table.
3. Use the main CAMera on the mounter to check whether the X and Y coordinates of each step of the component are consistent with the component center on the PCB, and check the angle according to the component location map in the process file Whether it is correct.
4. Copy the correct product program to the backup USB flash drive and save it.
5. Production can only be carried out after checking and checking.
Process and Supply Chain Management in SMT Chip Processing
SMT chip processing technology monitoring
SMT chip processing technology monitoring is an important activity to ensure quality and production efficiency. Take the reflow soldering process of key process as an example, the set temperature of the equipment is not equal to the actual temperature of the solder joints on the assembly board. In this case, the patch must immediately monitor the temperature curve and prevent defects by monitoring the process variables of the patch. Due to the automatic monitoring and response of process parameters, a large amount of investment is required, which is currently impossible for most domestic enterprises. In this case, the stability of the process can be achieved through manual inspection and monitoring, such as the DFM specification of the company, the general process of each process, the quality control points of key processes, and the temperature curve measured by manual timing.
2. Supply chain management of smt chip processing plant.
The supply chain management of SMT chip processing plants is actually the management of production materials, that is, to strengthen the management of the entire supply chain from the manufacturers of materials and components to the distributors and then to the manufacturers of final products. Stable raw material supply and quality is the basis for ensuring long-term stability of SMT quality. Lead free production material management is more strict than lead. The enterprise must seriously consider the physical process management from the purchase of components and other data to the identification, storage and online control of lead-free component PCB and process data to the delivery of lead-free finished products.
Supply chain management mainly controls the following aspects:
1. Strengthen the management of upstream suppliers.
Procurement control (evaluation and certification of components, PCBs, and process data when necessary and conditional).
3. Material preparation.
SMT part number and identification.
5. Material management automation.
6. Verification of SMT production line setting
Traceability and bill of materials.
Storage of components, PCBs and process data.
9. Train all personnel on the line.
