S30, using wave soldering, by metallic pin 340 and 200 soldering of pcb board；
S40, metallic pin 340 is cut to length C using cutter, to form lightning-protection module semi-finished product, A indicates metal
Pin 340 protrudes from the length at the back side of pcb board 200, and C is less than or equal to 1.5mm；
In the cutting process, the metallic pin 340 of existing surge protector is an individual device, not only cost
It is higher, and width and volume are larger, and the length for usually protruding from the back side of pcb board 200 is greater than 5mm, therefore all uses hand at present
The method of work excision, production efficiency is low, improves production cost, and this process carries out cutting using special cutter, not only
Efficiency is multiplied, and cutting size is also easier to accurately control.Particularly, the preferred 1.0-1.5mm of C, in this way, can both protect
Certain rigidity is held, the electric stress because generating when very high current flows through is avoided to impact metallic pin 340, it can also be to avoid
When protruding excessively high because of metallic pin 340, it may appear that the case where peak discharge occurs.

S42, electrical property detection is carried out to lightning-protection module semi-finished product；
Here, carrying out electrical property detection to lightning-protection module semi-finished product includes multiple projects, marked essentially according to relevant country
Standard carries out, most important of which is that test SPD starts voltage performance.
It is further comprising the steps of after step S50:
S60, ageing properties test is carried out to lightning-protection module.
Ageing properties test herein, refers to according to corresponding national standard, under certain environmental conditions, usually makes this anti-
Thunder module works 72 hours, determines that environmental condition influences the performance of this lightning-protection module with this.
This lightning-protection module passes through 110 integrated three pins of plate body being provided with pcb board 200, without using
A large amount of dedicated pin devices, structure is simpler, meanwhile, in the production process, using the automatic cutting of cutter, so as to significantly
Production cost and material cost are reduced, higher cost performance is reached.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
