Problems solved by technology

Each of the above methods has its own advantages and disadvantages: direct spraying of conformal paint, although the operation is simple, convenient, and easy to implement, it cannot truly protect the circuit board, and cannot achieve waterproof and shockproof. After a long time, the package may fail; Potting, cumbersome operation, low efficiency, high cost, and poor reliability; low-pressure injection molding, using low-pressure injection molding equipment, through a special mold, adjusting the corresponding injection pressure and time to complete the packaging of the circuit board, the mold design and production costs of this method are relatively low High, the characteristics of the glue itself have a great influence on the package

Abstract

The invention discloses a PCBA board packaging UV glue solution suitable for a piezoelectric array nozzle and the nozzle. The viscosity range of the UV glue solution is 5-25 cP at the temperature of 40-50 DEG C, the surface tension range is 20-40 mN / m, the density range is 0.8-1.2 g / cm<3>, and the pH value range is 6-8. The viscosity range of the UV glue solution is 10-15 cP, the surface tension range is 25-35 mN / m, and the density range is 0.9-1.0 g / cm<3>. The UV glue solution is colorless transparent or light yellow transparent glue. The PCBA board packaging UV glue solution suitable for the piezoelectric array nozzle is sprayed to the area, needing to be protected, of a PCBA board through a glue spraying assembly, and packaging protection of electronic components is achieved.

Description

technical field [0001] The disclosure relates to the field of circuit board packaging, in particular to a PCBA board packaging UV glue and a nozzle suitable for piezoelectric array nozzles. Background technique [0002] There are many packaging methods for PCBA (Printed Circuit Board+Assembly) boards, such as coating conformal paint on the surface of the circuit board, potting and low-pressure injection molding and other packaging methods. Each of the above methods has its own advantages and disadvantages: direct spraying of conformal paint, although the operation is simple, convenient, and easy to implement, it cannot truly protect the circuit board, and cannot achieve waterproof and shockproof. After a long time, the package may fail; Potting, cumbersome operation, low efficiency, high cost, and poor reliability; low-pressure injection molding, using low-pressure injection molding equipment, through a special mold, adjusting the corresponding injection pressure and time to...
