1. Visual inspection after wave soldering is completed to check whether the
appearance meets the requirements. There should be no false soldering, false
soldering, short circuit, open circuit and other undesirable phenomena. There is no
tin slag, tin bead and other sundries on the substrate, and the board surface is clean
and tidy without stains.
2. After passing the test, assemble the rubber shell, 50pcs per box, and separate each
layer with cardboard.
11. Precautions
1. The input voltage cannot exceed the voltage value specified in the specification to
prevent damage to the electronic board
2. The polarity of the positive and negative plugs of the power supply can not be
reversed. Reversed connection will burn the electronic board and cannot be used
normally.
3. Pay attention to anti-static measures when contacting the substrate during
processing, assembly, and operation to avoid damage to the substrate
4. After the product is packaged, please handle it gently to prevent collision and
damage to the substrate
