Sd Card Holder Push-type Terminal Block Connector Function Test And Precautions

Functional test
After installing push wire terminal block, perform a visual inspection first, then insert the test card for repeated plug-in and pull-out testing (recommended more than 20 times). At the same time, use a multimeter to check the connectivity of each pin of push in terminal block wire connector to ensure that there is no cold soldering or short circuit.

Precautions
Avoid using excessive flux, as residue may cause poor contact of push in wire terminal block. Control the welding time within 3 seconds/pin to prevent overheating and damage to push fit terminal block connector plastic parts. Keep the installation environment clean to prevent dust from entering the interior of the push connector block card holder and affecting contact.
