Microwave-medium plate low temperature brazing is a kind of new assembly technology, and the microwave-medium plate after soldering has good connecing
Ground, heat-conductive characteristic, can be effectively increased the power capacity of microstrip line, reduce loss.Microwave-medium plate design at the beginning of,
Microwave-medium plate surface is reserved pad and is used for the welding of microwave channel components and parts or insulator assembling, and in brazing process, solder is due to hair
Spy's use can flow on the pad with solderable coating, produces firm metal compound layer gold, causes metallization pattern short circuit,
Metal compound layer gold cannot thoroughly be removed substantially, not only affects the assembling of follow-up components and parts, and if in checkout procedure not and
Shi Faxian, may produce even more serious consequence after power on circuitry.By in advance welding resistance process being carried out to the pad of active position
The pollution of pad can be prevented effectively from, at present, the welding resistance method of microwave-medium plate low temperature brazing has two kinds, a kind of is welding resistance adhesive tape
Welding resistance method, a kind of is liquid film welding resistance method.
Adhesive tape main material in welding resistance adhesive tape welding resistance method be resistant to elevated temperatures low-molecular-weight resin, be usually used in large scale pad or
The welding resistance of plated through-hole.The method is cut into type for operator by hand according to the land pattern treating welding resistance, and adhesive tape sticking is arrived
Treat the land pattern position of welding resistance, after temperature is increased to melt solder, due to the high-temperature stability of adhesive tape itself, treat welding resistance
Land pattern position is protected by adhesive tape, cannot be diffused into below adhesive tape after melt solder, plays physical isolation welding effect.

Band, because through high temperature, part colloid departs from adhesive tape and remains on pad, needs to increase matting, cleaning is improper may be to micro-
Other circuit parts of ripple dielectric-slab cause to damage；Adhesive tape molding relies primarily on tailors by hand, and level is uneven, process consistency
Poor, low production efficiency.
Liquid film welding resistance method, main material is liquid photosensitive type solder mask, and ink is by photoresist component and thermosetting
Change resin Composition to synthesize in proportion, there are light solidity and thermosetting characteristics.The method flow process be followed successively by pre-treatment, weldering film, preliminary drying,
Exposure, development and after bake, pre-treatment is the adhesion in order to go the removal of impurity and ensure liquid film and printed circuit board, and weldering film is used for
Liquid film is coated with a printed circuit board, preliminary drying is for evaporation solvent, exposes for needing to stay on a printed circuit board
Ink reacts through irradiating, and is not taken off in development it is not necessary to stay ink on a printed circuit board to be washed in development
Fall exposed pad, development is not need to stay the ink on printed circuit board to wash away, and stays and needs to stay printed circuit board
On ink shield, after bake is used for making ink thoroughly solidify.The method manufacture process complicated it is desirable to precise control technique
Parameter, due to technical maturity it is not easy to quality problems, is widely used in the manufacturing of few kind, typical products in mass production, its work
Skill characteristic creates the method and more relies on production equipment, needs to put into great amount of cost, for equipment purchase and maintenance, general
