Many companies are beginning to use SMT second-hand placement machines, and require relatively stable placement machines, low failure rate, easy maintenance, and maintenance costs are very important. Therefore, there are still many concerns about buying a second-hand placement machine. So, what should you pay attention to when buying a placement machine?
Samsung is the most cost-effective one among foreign brands, the price is relatively low, most of the products can be made, the production capacity is also good, and it is very practical. Operation and maintenance are also easy. The accessories are original, there are many imitations, and the price is cheap, so Samsung uses more in China. Because of the above advantages, there are more second-hand Samsung products!
Before many companies first go to the SMT line, they will face a choice,
entangled between new machines and second-hand placement machines. Tangled between other machines and Samsung, maybe I heard that Samsung is unstable. In fact, it is a kind of preconceived consciousness of other brands, or just heard of it. With the development of SMT technology up to now, the machines are relatively stable. In fact, it is not the key to what machine you build. The key is your technical, management, and process capabilities. Can the so-called people, machines, materials, methods, and environment be able to do well? There is no need to have a big prejudice against Samsung phones, just do what you can when you buy the phone! For those who expect fast returns, small risks, and less investment, it is still recommended to buy a second-hand placement machine.
The placement machine required to be selected is relatively stable, has a low failure rate, is easy to maintain, and the maintenance cost is very important. Therefore, there are still many concerns about buying a second-hand placement machine. So, what should you pay attention to when buying a placement machine? The following aspects are for reference:
1. It depends on whether the machine is overseas
The running time of overseas placement machines is short. This is determined by the difference between foreigners and our working methods. Everyone should know that foreign companies work on an 8-hour work day, with people moving and shutting down. Look at the country again, no domestic boss will let the machine idle. The overseas placement machines are well maintained. Machine maintenance is carried out from time to time, daily maintenance, monthly maintenance, and major movement adjustments every quarter. In this way, second-hand smt film machine failures are relatively rare. Many suppliers use this as a selling point and must be added to the identification.
In fact, the domestic machine has been refurbished and maintained (refurbishment does not mean the appearance of painting, but the internal precision parts, the vulnerable parts are replaced and the precision adjustment test is carried out according to the new machine standard), all the wearing parts are replaced, the appearance of the second-hand placement machine will be Like the new machine, it can guarantee more than 90% of the new machine's functions and can be produced at full speed. The reliability and stability are comparable to the new machine, and the price is about 1/3 of the new machine. Large companies generally require a three-week refurbishment, calibration, debugging, and aging time for a second mobile phone (in stock), while the general second-hand dealer may ship it within a week. Many friends will be entangled after deciding to choose second-hand equipment. There are too many second-hand dealers in China. There is a mixture of fish and dragons. It is not a good choice at all. It is often introduced by friends, but this is not very safe. After all, it is economic and social.
Recommendation: Find a large-scale supplier. Regardless of the equipment maintenance and refurbishment in the early stage, the mid-term training, and the later service, they are all done in front of the small company. You can inspect the suppliers and visit the customers they serve.
2. Whether the machine recommended by the supplier is suitable
When many people heard that the customer wanted a placement machine with a line configuration of 300,000, they immediately recommended a machine without knowing what the customer did, how big the PCB board, what components, and what process requirements. This is very irresponsible. Customers buying machines should be decided according to the characteristics and output of their products. Since there are too many second-hand placement machines on the market and the speeds are different, customers must do an inspection before buying smt equipment, shop around, and buy cost-effective machines.
Three, buying second-hand smt placement machine does not provide services
This practice is popular in many companies, but it is not recommended for newcomers. It is cheaper if the service is not included, but if there is a problem later, it is not only time that is lost. Please hire an engineer outside, they have the final say in time, and they have the final say in price. For long-term development, large companies that provide services will do a good job of service. In addition to maintenance, they will also perform periodic maintenance. Large companies provide warranty services all over the country, and there are offices throughout the country, which ordinary second-hand dealers cannot do!
