Description
Technical Field
The utility model relates to the technical field of circuit board processing, in particular to an adjustable fixture tool for circuit board spraying.
Background
The three-proofing paint is a special formula paint used for protecting circuit boards and related equipment from being corroded by environment. The three-proofing paint has good high and low temperature resistance; the cured transparent protective film has excellent insulating, dampproof, anticreep, shockproof, dustproof, anticorrosive, ageing-proof, corona-proof and other performances. Under real conditions, such as chemical, vibration, high dust, salt fog, humidity, high temperature and other environments, the circuit board can generate problems of corrosion, softening, deformation, mildew and the like, so that the circuit board circuit is in fault. The three-proofing paint is coated on the surface of the circuit board to form a layer of three-proofing protective film (the three-proofing refers to dampproofing, salt fog proofing and mildew proofing). The circuit board without the three-proofing paint under the conditions of chemical substances (such as fuel, coolant and the like), vibration, moisture, salt spray, humidity and high temperature can be corroded, mould grows and short circuit is generated, and the circuit is caused to malfunction. In addition, since the three-proofing paint can prevent electric leakage, higher power and closer printed board spacing are allowed. Thereby the purpose of miniaturization of the element can be satisfied.
