SMT equipment: the choice of placement machine is the key The general SMT production process includes solder paste printing, patch and reflow three steps, so to form a complete SMT production line, it must include the equipment to implement the above process steps: printing machine, paste Tablet and reflow ovens. In particular, placement machines often account for more than 70% of the entire production line investment, so the choice of placement machines is the key. SMT machine manufacturers currently produce a large number of SMT machine manufacturers, the structure is also different, but according to the scale and speed can be roughly divided into large-scale high-speed machine (commonly known as "high-end machine") and medium-sized medium-speed machine (commonly known as "middle-range machine") There are other small placement machines and semi-automatic/manual placement machines. The price of a mainframe is generally 3 to 4 times that of a medium-sized machine. Manufacturers of large-scale high-speed placement machines mainly include Panasonic, ASM, Fuji, Yamaha, JUKI, Assembleon, etc. Manufacturers of medium-sized medium-speed placement machines mainly include Hanhua, Mirae, Mydata, Walasse, and Woody. Regardless of mainframe manufacturers or medium-sized machine manufacturers, the recommended SMT production line is generally composed of two placement machines: a chip chip placement machine (commonly known as high-speed placement machine) and an IC component patch Machine (commonly known as high-precision mounter), so that their responsibility, contribute to the placement machine to play a high patch efficiency. Hua Zhizhen excellent combination of placement machine program: 1, MC812 + H806: can solve the problem of too many materials used station is not enough, PCB board is too large and imported equipment and other problems! Faster mounting and higher precision, can be mounted 0.4mm pin pitch IC (such as: QFP, BGA and other packages), the actual line capacity of 35,000 points / hour or more. Applied to smart home appliances, automotive electronics, avionics, consumer electronics, etc. 2. MC812+MC69T: It can be applied to ultra-long PCB board placement, with faster mounting speed, higher precision, less power consumption, and more economical benefits. The actual capacity of the entire line is 35,000 points per hour or more. It can mount 0.5mm pin pitch IC (such as: SOP, QFP and other packages), used in power supply, small household appliances, intelligent lighting and so on. 3, MC812 + H803: can solve a variety of irregular materials and conventional materials combined mounting problem. Faster placement and higher precision, 0.3mm pin pitch IC (such as: QFP, GBA, etc.) can be mounted, and the actual production capacity of the entire line is more than 30000 points/hour. High application capabilities: mobile phones (such as shielded covers), military, high-precision intelligent controllers. Different production environments require the use of different types of placement machines. Production scale is the first issue to be considered. Whether the machine meets production requirements depends on which components need to be mounted on the circuit board, how many components need to be mounted, and what is the specific production environment. When buying a new placement machine, you first need to specify the following questions: How many different types of components can be used to produce the circuit board? How many different types of components will be used? What kinds of components will be used? What kinds of components will be used? How much is there to change? What is the average number of components per panel? How many boards can be produced per hour? What level of return on investment can be achieved? What is the cost? Successful component placement is often associated with a variety of devices. Understand the various aspects of the entire process, you can easily make favorable decisions based on the advantages and disadvantages of different placement machines.
Custom Piezoelectric Components
The piezoelectric ceramic sound-generating element, especially a lead-free piezoelectric ceramic sound-generating element, is mainly composed of metal flakes and piezoelectric ceramic flakes. The sound pressure generated by this new structure piezoelectric sounder is proportional to the number of piezoelectric ceramic sheets. By increasing the number of piezoelectric ceramic sheets, the required large sound pressure is easily achieved.
