Galia pasirinkimas elektrinis litavimas lygintuvas
The power of the soldering iron used is too high, which can easily burn out the components (usually when the temperature of the junction of the transistor and transistor exceeds 200 degree , it will burn out) and cause the printed wires to detach from the substrate; The power of the soldering iron used is too low, the soldering tin cannot be fully melted, the flux cannot evaporate, the solder joints are not smooth and firm, and it is prone to false soldering. Generally, it is used for welding integrated circuits, printed circuit boards, CMOS circuits, decorating transistors, IC type recorders, televisions, and conducting ordinary circuit experiments. It is generally recommended to use 20W. For repairing vacuum tube machines such as biliary machines and old instruments, it is recommended to use 35W, while for externally heated ones, it is recommended to use 45W. For welding the wiring of large transformers and grounding main lines on metal substrates, it is recommended to use internally heated 50W, externally heated 75W, and some higher power applications.
Yra įvairių formų iš litavimo lygintuvo galvučių, ir the key to choosing one is to regular keep a certain amount of solder, greitai ir efektyviai lydymo the solder on the joint, be gamybos lydmetalio jungčių, persidengia, arba kabo, be burrs, ir be žalingo the board and components. If the solder jungtys on the machine are brand new and bright, the tin dipping section of the slitavimas iron head can be larger, and a flat or elliptical head can be used for fast heat transfer, natural operation, and convenience. The tin oxide layer is thick, and the solder iron tip is reliatyviai sharp, making it easy to break through.
Due to the high density of components, it is need to use corresponding sharp iron alloy heads to avoid burns and soldering. When assembling and dissembling IC blocks, special shaped solder iron heads are often used. Kartais, due to the inability to solder and the need to avoid damageging plastic parts, bent solder iron heads are used. Of course, it also depends on each person's operating habits and hobbies.
How to choose an elektrinis litavimas lygintuvas
1. Pasirinkimas šildymas metodas pagrįstas elektrinis litavimas lygintuvas
(1) Pasirinkimas iš vidinis ir išorinis šildymas: Kai galia yra tas pats, the temperatūra of the internal heating elektrinis litavimas lygintuvas is didesnis nei tas išorinis šildymas elektrinis litavimas lygintuvas.
(2) When low-temperature welding is required, a voltage regulator should be used to control the temperature of the electric soldering iron. The temperature of the electric soldering iron is closely related to the power supply voltage. In practical use, the temperature of the electric soldering iron is often reduced by lowering the power supply voltage.
(3) kontrolė temperatūra pagal reguliavimas the prailginimas ilgis of the litavimas geležis galvutė.
(4) Yra yra keli metodai stabilizuoti the temperatūra of electric litavimas lygintuvai: montavimas a reguliuojamas galia tiekimas to prevencijos keitimai in the power supply network; Keep a certain volume, length, and shape of the slitavimas lygintuvas galvutė; Naudojimas a konstanta temperatūra elektrinis litavimas lygintuvas; Išlaikyti a pastovus patalpų temperatūra; Venti natūralus vėjas arba elektriniai ventiliatoriai, etc.
2. Selection of electric soldering iron power
(1) Kai Suvirinimas mažos galios varžinis ir talpiniai komponentai, tranzistoriai, integruotos grandinės, spausdintos grandinės plokštės, trinkelės arba plastikiniai laidai, it is patartina to naudoti 30-45}W išoriškai šildomas arba 20W viduje šildomas litavimas lygintuvai. The best choice for application is to use a 20W internal heating electric litavimas lygintuvas.
(2) Kai suvirinimas the suvirinimas taškai of general structural products, such as wire rings, wire claws, heat displepation fins, įžeminimas trinkelės, etc., it is recommended to use 75-100}W electric litavimas lygintuvas.
(3) For large welding points, such as metalas rėmas jungtys, suvirinimas trinkelės, etc., it is rekomenduojama to use 100-200W elektrinis litavimas lygintuvas.
