In a printed circuit board (PCB) in a product such as a home appliance or a communication device; more specifically, it relates to a resin distribution device which can be applied to various fields in accordance with a simple structure and can be used in a variety of applications. Maintenance and repair of the equipment, easy disassembly of the parts to be cleaned, maintenance of the maintenance cost of the 0 repair, use regardless of the type of the resin, and easy inspection of the head state make it possible to maximize the reliability of the device. [Prior Art] In general, a viscous solution (resin) such as an epoxy resin is dispensed in order to mount a surface-mount component (wafer, IC) on a printed circuit board, or to remove a semiconductor component Protected in the external environment, coating and sealing the periphery of the wafer, and under-coating of the underfill, the resin distribution device (dispenser) is commercialized by various techniques. Such a resin distribution device has recently been developed and commercialized as a surface mounter of 65 000 wafers/hour or more with the acceleration of industrial technology. In order to cope with such a high-speed wafer assembling machine, a resin dispensing device of high speed and high precision is required. In particular, the resin distribution device used in the surface structure of a semiconductor wafer not only ensures the correctness and rapidity of solution distribution, but also fails to reduce the defective rate if the dispensed quantitative resin is not properly discharged. - (2) (2) 1250927 Therefore, it is required to repeatedly discharge the solution at a high speed for long-term use; and to repeat the action of the same amount or area within a very small tolerance range. In order to cope with such a request, recently, in order to increase the discharge rate of the solution (resin), it is disclosed that the injection pressure is added to the pump method or the vacuum is applied.

(3) '1250927 However, in the case of a large part, the number of points can be increased to match. This is especially the case with silicone engineering. Moreover, the setting conditions of the resin distribution device to be used will also change due to the viscosity (viscosity), flow viscosity reduction (shape retention), flow characteristics, and adhesion characteristics of the applicable adhesive (resin), among which the most important It has a great influence on the distribution pressure and the distribution time (allocation speed). However, in the case of the distribution of the resin in the past, the equipment made up of the characteristics of the resin (·adhesive) cannot provide interchangeability, and the equipment is very complicated to implement, and the parts to be cleaned by the applied resin are required. The decomposition, the difficulty of assembly, the complexity of the adjustment of the point bar (str 〇ke), and the realization of the buffer function of the front end have very complicated shortcomings, and the exchange work for the needle bar is complicated. Disadvantages. That is, 'the most recent actual situation is that high-speed wafer assembly is commercialized' and it is required to have a high-speed distribution device that can actively respond to this actual situation; however, conventional distribution devices have: very complicated and The disadvantage of the heavy weight of the equipment; the frequent failure of the operation due to the large volume, and the shortcomings to be repaired due to the failure; the disadvantages of the decomposition and assembly of the equipment; and the decomposition before the cleaning operation of the cleaning parts The disadvantage of difficult work.
