SMT placement machine hardware and software considerations


No matter what machinery and equipment are in use, they must be maintained. This will not only maintain the stability and accuracy of the equipment, but also extend the life of the equipment. The smt placement machine is of course no exception.

Let's talk about the precautions of some objective factors of the placement machine


one. SMT placement machine hardware

1. For power supply, it is recommended that all SMT machines be connected to UPS and voltage regulators. Pollution of the grid voltage causes voltage instability, causing burn-in of the board, power failure will damage the computer hard disk, and the risk of scrapping the board in the furnace, etc.

2. Air supply, compressed air must be cleaned of dust and water Drop onto the board, drop onto the SLEEVE and RV reading head, resulting in frequent RVD reporting, and the new machine will directly burn out the vacuum generator;

3. Temperature and humidity. The best temperature for SMT equipment is 24±4 degrees, and humidity is 45%-75%. Too high temperature causes equipment downtime, frequent occurrence of various minor problems, stuttering, and too low humidity, which can cause high static electricity. Lead to a spike in the throwing rate

4. Cleanliness and SMT dust are very important to the quality of the furnace. The materials above 0201 should be run in a 30W dust-free workshop. High-speed machines are afraid of dust. Larger dust is likely to cause suction nozzles. Blockage and frequent leakage of flying materials. Secondly, it affects various sensors, especially BE sensors, which leads to inaccurate measurement of the thickness of small materials. Thirdly, it is easy to accelerate the wear of the slider and the guide rail.

5. Dust removal of the electrical control part. Generally, the equipment with more than three years or poor dust-proof environment in the workshop should be checked and dusted in the first quarter, and the new machine should be checked and dusted once a year. Prevent the occurrence of bad equipment failures such as insufficient heat dissipation, crashes, board burns, and poor contact after the board is loose.

6. Skills of engineers, many companies produce under the condition that the above aspects are not well controlled. When the machine is first bought, there is no problem in the first two or three years. There are more and more follow-up problems, the quality is getting worse and the maintenance costs are getting more and more. High, the boss is reluctant to pay a high price for good professional equipment engineering. If there is a problem, the equipment engineering and technical personnel will be dismantled regardless of whether the equipment engineering and technical personnel are qualified or not. The salary I paid is several times the price for accessories

two. smt placement machine software

In terms of software, the main point is the virus, where did the virus come from, and the USB flash drive. It is recommended to use a local area network to share the program, or use a high-end anti-virus write-protected USB flash drive. Ordinary USB flash drives are wired to control the risk of spreading viruses and are also the number one source of viruses. Programs are stored in the SQL database. Any problems caused by wired control poisoning will occur., For example, if the material is reversed for unknown reasons, the program cannot take effect on the machine when the line control is changed, the OIS cannot be connected, the image cannot be returned to the line control, the program cannot be transferred to the machine, and so on.
