旋转东莞电位器使用注意要点
1.电位器之端子在焊接时应避免使用水容性助焊剂,否则将助长金属氧化与材料发霉;避免使用劣质焊剂,焊锡不良可能造成上锡困难,导致接触不良或者断路。
The 1potentiometer terminal in welding should avoid the use of water capacitive flux, otherwise it will contribute to metal oxide and molding material; avoiding the use of inferior flux, poor soldering may cause difficulty on tin, lead to poor contact or breaker.
2.电位器之端子在焊接时若焊接温度过高或时间过长可能导致对电位器的损坏。插脚式端子焊接时应在235℃±5℃,3秒钟内完成,焊接应离电位器本体1.5MM以上,焊接时勿使用焊锡流穿线路板;焊线式端子焊接时应在350℃±10℃,3秒钟内完成。且端子应避免重压,否则易造成接触不良。
The 2potentiometer terminal in welding when the welding temperature is too high or too long can cause damage to the potentiometer. Pin type terminal welding should be at 235 degrees C +5 C,3 seconds to complete, the welding shall be from the potentiometer body above 1.5MM, welding do not use solder flow in circuit board; welding wire type terminal welding should be at 350 degrees C +10 C,3seconds. And the terminal should avoid weight, otherwise easily lead to poor contact.
3.电位器之电阻体大多采用多碳酸类的合成树脂制成,应避免与以下物品接触:氨水,其它胺类,碱水溶液,芳香族碳氢化合物,酮类,脂类的碳氢化合物,强烈化学品(酸碱值过高)等,否则会影响其性能。
The 3potentiometer resistance body mostly adopts carbon acids made of a synthetic resin, and the following items: should avoid contact other amines, ammonia, alkali solution, aromatic hydrocarbons, ketones, lipid, hydrocarbon, strong chemical ( high pH ), otherwise it will affect its performance.
