Description
Technical field
The present invention relates to electronic component protection technology fields, and in particular to a kind of electronics member applied to electronic component
Device coating composition.
Background technique
Electronic component is the component part of electronic component and electric small-sized machine, instrument, itself is often by several parts
It constitutes, it can be general in similar product;Often refer to electric appliance, radio, the industry such as instrument certain parts, as capacitor, transistor,
The general name of the sub- device such as balance spring, clockwork spring.It common are diode etc..
Because of the requirement of product characteristic, the back edge amount of existing low melting point cofired stack chip electronic component, i.e., interior electrode spacing
The distance of product edge is smaller and smaller.Due to the limitation of production equipment machining accuracy, it is exposed that most product will appear interior electrode
Phenomenon, need to be in product surface coating protective layer, to cover exposed interior electrode.The protection coating of surface coating at present substantially has
Two kinds, one is based on organic material, product surface is applied to by mechanical means after the firing of product external electrode, through adding
It is formed after heat drying, solidification, is not required to through high temperature firing, high temperature can not be resistant to, the combination of coating and product is insecure；It is another
Coating need to be burnt into through (700-900 DEG C) of high temperature, and coating and porcelain body form fine and close overall structure after firing, but in sintering process
In, because the sintering for the 15%-20% that wellability of the coating material to product porcelain body and electrode material is inconsistent and coating is intrinsic is received
Gap between volume change caused by the thermal expansion of shrinkage and porcelain body, coating easily crack.Electricity in the prior art simultaneously
