It's no use washing the nozzle with alcohol, so it's clean as well.
1. clean useless, the inner thimble whether grinding smooth2., the lower part of the nozzle sealing ring is leaking?3. there is an atomizing knob on the side of the nozzle. Is it possible that you didn't spray well?4. whether the gas is broken, pressure is stable. There is no injection of flux at the same time expired?5., the top of the nozzle cap is in direction, turn 90 degrees to see.6., the spray pressure is too large, hit the rebound board.7. is the distance between the shower nozzle and the board too close?8., the nozzle itself ability problem, uneven what is the matter, you fax paper test, or the naked eye to see?. Some guns are not uniform.If you can spray homogeneously, pull big fan and distance, the flux will be very uniform, this is not a big problem.
There may be inside the thimble without grinding along the inside of the nozzle, the lower seal leakage, a side nozzle atomization knob, no good atomization nozzle top gun cap is in the direction of the spray pressure is too large, hit the board rebound, nozzle and board too close.Soldering is let board welding surface directly with high temperature liquid tin to achieve the purpose of welding, the high temperature liquid tin keep a slant, and by a special device to make the liquid tin forming a similar wave phenomenon, so called "wave", the main material is solder.Flux: a chemical that helps and promotes welding processes and has a protective effect and prevents oxidation reactions in welding processes. Flux can be divided into solid, liquid and gas. The main auxiliary heat conduction, removing the oxide, reduce the surface tension of welding material, welding material removal is surface oil, increase the welding area, prevent oxidation and other aspects, in several aspects of the key role of the two is: "to remove oxides and" to reduce the surface tension of welding material".
1. nozzle wear --- replace nozzles or accessories.2. nozzle clogging ---- cleaning and maintenance.
The sprinkler ST-6 is broken. I have it here
