What Should be Paid attention to When Cleaning PCBA
After the PCBA is processed and welded, some flux residues will remain on the surface. If the surface cleanliness cannot be effectively guaranteed, it may affect the use time of the PCBA, so effectively cleaning the circuit board in manufacturing process is a very important step. So what should we be pay attention to when cleaning the PCBA board? 1. After the PCBA board is soldered, the flux residue will corrode over time, so it should be cleaned in time after soldering. 2. When cleaning the PCBA, we must wear an electrostatic wristband and a protective mask. 3. When cleaning the PCBA, its necessary to protect the components and logos on the board to prevent the cleaning agent from entering the unsealed components, so as not to cause damage to the components. 4. Some electronic components are prohibited from contacting special cleaning agents, such as: key switches, buzzers, batter...
