How to use the soldering iron correctly
Welding technology is a basic technology that radio enthusiasts must master. It requires a lot of practice to master.
1. For the selection of suitable solder, the low melting point solder wire for soldering electronic components should be used.
2. Flux, dissolved in 75% alcohol (by weight) with 25% rosin as a flux.
3. The soldering iron should be tinned before use. The specific method is: heat the soldering iron. When the solder can be melted, apply flux, and then evenly spread the soldering iron on the soldering iron to make the soldering iron evenly eat. A layer of tin.
4. Soldering method, sanding the pads and components with fine sandpaper and applying flux. Dip a proper amount of solder with a soldering iron tip and contact the solder joint. After the solder on the solder joint is completely melted and immersed in the component lead, the soldering iron tip gently lifts up the solder joint along the lead of the component.
5. The welding time should not be too long, otherwise it will easily burn the components. If necessary, the pins can be clamped by the tweezers to help dissipate heat.
6. The solder joint should be in the shape of a sine wave peak, the surface should be bright and smooth, no tin thorn, and the amount of tin is moderate.
7. After the welding is completed, the residual flux on the circuit board should be cleaned with alcohol to prevent the flux after the carbonization from affecting the normal operation of the circuit.
8. The integrated circuit should be soldered last, the soldering iron should be grounded reliably, or it can be soldered with residual heat after power off. Or use an integrated circuit socket, solder the socket and then plug the integrated circuit.
9. The soldering iron should be placed on the soldering iron stand.
Continuously monitoring critical asset parameters such as vibration, temperature, speed, and numerous other condition indicators is a proven method for anticipating and preventing mechanical failures – proven in tens of thousands of industrial facilities around the world by delivering tangible benefits such as:
• Improved protection from catastrophic failures • Better machinery reliability/availability • Fewer process interruptions • Enhanced maintenance/outage planning • Lower maintenance and repair costs • Longer intervals between outages • Reduced insurance premiums And when it comes to protecting and monitoring critical machinery, one name has proven itself above all others: Bently Nevada* from GE Measurement & Control.
