Background technology
With the development of microwave technology, the frequency more and more higher of microwave module, the cavity used in microwave module engenders
Deep chamber or narrow cavity configuration, deep chamber or narrow cavity configuration cavity effectively shield electromagnetic interference, improve the transmission quality of microwave signal.
In existing process, to improve cavity and microwave circuit boards burn-back penetration rate, conventional electric iron wards off tin on cavity, and deep chamber or
The appearance of narrow cavity configuration cavity, is limited by cavity body structure part, can not be warded off tin in deep chamber or narrow cavity edge with electric iron, be warded off tin not
In place, influence cavity and microwave circuit boards burn-back penetration rate, the final quality for influenceing product, in addition, with electric iron in deep chamber or
Operate and its inconvenient, add heavily to the difficulty of the work on narrow chamber.
To solve the deficiency of existing process, tin method is warded off on deep chamber or narrow chamber the invention provides one kind, this method is led to
Cross setting and rationally effectively ward off process of tin flow, by the gold plated copper sheets of suitable size, deep chamber or narrow cavity edge is warded off tin completely,
Guarantee is provided for follow-up cavity and microwave circuit boards burn-back penetration rate, ensure that the quality of product.The letter of the inventive method step
It is single, easy to operate, can produce in enormous quantities, in the case where not increasing equipment investment, improve the quality of product.
The content of the invention
The deficiency of tin can not be effectively warded off in the cavity of deep chamber or narrow cavity configuration to solve existing process with electric iron, this
Invention provides one kind and wards off tin method on deep chamber or narrow chamber.This method mainly includes:
Step 1: make gold plated copper sheets.According to deep chamber or narrow cavity configuration and size, make what is be engaged with cavity body structure and size
Copper sheet, then copper sheet surface gold-plating.
Step 2: before tin is warded off, oxide is removed in advance.Cavity is placed in plasma cleaner, set clear
Parameter is washed, with strong cleaning, removes cavity tin region surface oxide to be warded off.
Step 3: being preheated in thermal station, scaling powder, model are sprayed:EF-9301, upper solder, the solder compositions percentage
Than:Sn96.5%, Ag3%, Cu0.5%.Cavity is placed in the thermal station that temperature is 240 ± 5 DEG C and preheated, then to cavity
Spray one layer of scaling powder, model in tin region to be warded off:EF-9301, then add appropriate solder stick to cavity tin region to be warded off again.
Step 4: gripping gold plated copper sheets with tweezers, it is placed on the solder of fusing, is rubbed back and forth in cavity tin region to be warded off
Wipe, its cavity is warded off tin.
Step 5: cleaned the cavity after tin is warded off.The cavity after tin will be warded off and be first put into that to fill ABZOL CEG CLEANER clear
Hot brew cleaning, scavenging period 300-350s in the vapour phase cleaning groove of lotion, then be cleaned by ultrasonic, scavenging period is
100-120s, finally it is put into absolute ethyl alcohol and carries out hairbrush scrub, naturally dry.
Beneficial effect:One kind provided by the invention wards off tin method on deep chamber or narrow chamber, the advantage is that, tin is warded off in cavity
Before, cavity adhesive force is improved, is improved weldering with the oxide in the strong cleaning model removal cavity of plasma cleaner in advance
The wellability of tin, ward off tin for follow-up cavity and provide suitable environment, eliminating influences the undesirable element that cavity wards off tin quality;Separately
It is outer it is used in the present invention carries out cavity with tweezers gripping gold plated copper sheets and wards off tin mode, use electric iron mode relative to tradition, behaviour
Work is more simple, convenient, efficient, wards off tin without dead angle.The present invention is adapted to produce in enormous quantities, is worthy to be popularized.
Brief description of the drawings
Fig. 1 is flow chart of the method for the present invention.
Embodiment
