Second hand SMT wire placement machine
Many companies have started to use SMT second-hand mounters, and need relatively stable mounters, whICh have low failure rate, are easy to maintain, and maintenance costs are very important Therefore, there are still many concerns about buying second-hand chip mounters So, what should you pay attention to when purchasing a chip mounter?
3Star is one of the most cost-effective foreign brands. Its price is relatively low. Most of its products can be manufactured, and its production capacity is good. It is very practical. Operation and maintenance are also easy. The accessories are original, there are many imitations, and the price is cheap, so 3-star is used more in China. Due to the above advantages, 3 stars have more second-hand products!
Before many companies enter the SMT production line for the first time, they will face a choice,
EntangLED between the new machine and the used placement machine Other machines are entangled with 3 stars. Maybe I heard that 3 stars are unstable In fact, this is a preconceived awareness of other brands, or just heard of it With the development of SMT technology, the machine is relatively stable up to now In fact, this is not the key to what kind of machine you build The key is your technology, business, and process capabilities Can the so-called people, machines, data, methods and environment do well? There is no need to have a great prejudice against 3-star mobile phones. Do your best when buying mobile phones! For those who expect fast returns, with SMAll risks and less investment, it is still recommended to buy second-hand chip mounters
The placement machine to be selected is relatively stable, low failure rate, easy to maintain, and maintenance cost is very important. Recall that there are still many concerns about purchasing second-hand SMT machines. So, what should we pay attention to when purchasing the mounter? The following aspects are for reference:
1. Depends on whether the machine is abroad
The operation time of foreign chip mounters is short. This is determined by the differences between foreigners and our working methods. Everyone should know that foreign companies work eight hours a day, and employees move and close. Look at this country, no domestic boss will let the machine idle. The overseas mounter is well maintained. Machine maintenance is carried out irregularly, daily maintenance, monthly maintenance and quarterly major movement adjustment. As a result, there are relatively few failures of second-hand smt film applicators. Many vendors use this as a selling point and must add it to the logo.
In fact, domestic machines have been refurbished and maintained (refurbishment does not mean that the appearance is painted, but that the internal precision parts and wearing parts are replaced, and precision adjustment tests are conducted according to the new machine standards). All wearing parts have been replaced. The appearance of the second-hand SMT machine will be the same as the new machine. It can guarantee more than 90% of the functions of the new machine, and can be produced at full speed. The reliability and stability are equivalent to the new machine, and the price is about 1/3 of the new machine. Large companies usually require 3 weeks of refurbishment, calibration, debugging and aging time for the second mobile phone (inventory), while ordinary second-hand dealers may ship within one week. Many friends will be in trouble after they decide to choose second-hand equipment. There are too many second-hand dealers in China. A mixture of fish and dragon. This is not a good choice at all. It is usually introduced by a friend, but it is not very safe. After all, this is an economic and social problem.
Recommendation: Look for large suppliers. Whether it is early equipment maintenance and renovation, mid-term training, or late service, they are all completed in front of small companies. You can check 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 300000 line mounter, they immediately recommended a machine without knowing what the customer had done, how big the PCB board was, what components, and what process requirements. This is very irresponsible. Customers should purchase machines according to the characteristics and output of their products. Because there are too many second-hand SMT mounters in the MARKet, and the speed is different, customers must check before buying SMT equipment, go around, and then buy a cost-effective smt mounter.
3. No service is provided for buying second-hand smt placing machines
This practice is popular in many companies, but is not recommended for novices. If services are not included, the cost will be lower, but if problems occur in the future, more than time will be lost. Please hire an engineer outside. They have the final decision on time and price. For long-term development, large companies that provide services will do a good job. In addition to maintenance, they will also carry out regular maintenance. Large companies provide warranty services all over the country and have offices all over the country, which is impossible for ordinary second-hand dealers!
