Is it important to check the soldering iron after soldering?
Nakon zavarivanje, it je potrebno to check whether there are any missing lemljenja, weak lemljenja, i komponenta kratki krugovi uzrokovani by lemljenje protok. Zavarivanje je teško to otkriti. You can use tweezers to the component pins and gently pull them. If trese is found, repair the soldering immediately.
The electric soldering iron is the the most commonly used tool in electronic welding. Its function is to convert electric energy into heat energy to toplinski and zavar te lem spojevi. A large part of its success depends on how well it is controlled. Therefore, from a certain perspective, the electric soldering iron The use of it relies on a sense of technique.
Općenito speaking, the the greater the power of the electric soldering iron, the greater the heat, and the higher the temperature of the soldering iron tip. Općenito, a 20W internal grijanje lemljenje željezo je dovoljno zavarivanje zavarivanje tranzistor i integrirano krug elektronički komponente. Excessive power can can easily burn components, because DIODES and tranzistor will burn out if IF THEIR Junction TEMPERATURE EXEDS 200 Degree . Međutim, in the production of tube pojačala uglavnom based on scaffolding zavarivanje, the power of the soldering iron should be higher, and you can choose between 35W-45W, or even higher.
It is worth noting that when zavarivanje the circuit, the time should not be too long or too short. If the time is too long, it will be easy damaged. If the time is too short, the solder will not be full melted, resulting in the solder joint being not smooth and firma, and may also produce a false solder. Općenito, The most appropriate time must be completed within 1.5s to 4s.
Lemljenje je a fusible metal, i the most common used one is solder wire. The function of solder is to connect the component pins to the connection points of the printed circuit board. The choice of solder has a great impact on the quality of zavarivanje. Danas, the most commonly used solder wire is generalno kolofonija solder wire al a žica, but the subdivision is also very particular. Among them, the the silver-containing solder wire to do ne sadržalo voda je je of naravno the top grade.
Također vrijednost mentioning is the the solder apsorber, which is very practical for newces. It is always easy to get solder everywhere when using a soldering iron for the first time. The solder absorber can help you remove excess solder from the circuit board. In addition, the solder absorber is very effective and useful when dismantling multi-pin integrated circuit devices. It can suck out all the solder joints. Međutim, it is potpuno nepotrebno za ljudi who are skilled in using a soldering iron. A lemljenje željezo can potpuno replace it funkcija. The component can can be easy removed by melting away the solder joints.
Prije zavarivanje, predlemljenje tretman treba biti izvedeno on the component pins or the soldering parts of the circuit board.
Remove the oxide layer from the the zavarivanje part - you can use a broken saw blade to make a knife and scrape off the oxide layer on the surface of the metal olovo to reveal the metallic luster of the pin. The printed circuit board can be poliran with fine gauze paper and then coated with a layer of rofo kolofon alkohol otopina.
