  • Does flux not clean harm to PCBA? Nov 27 , 2021
    When the residue remains on the PCBA, it is easy to cause the adsorption and condensation of moisture and dust, and may also cause poor contact in the ICT test, which affects the accuracy of the test result. Under high temperature conditions, the flux residue may be rearranged directly. Cause a short circuit or leakage. For high-frequency and high-speed circuits, even if the circuit is normal, the...
