    the fourth step of produducing SSR: assemble

    Separate the circuit board and press it one by one against the copper pillar, then fit the circuit board into the shell. Then start bending the pipe corners. Fold the left pipe corner onto the circuit board, the middle one onto the left copper pillar, and the right one onto the right copper pillar. Use soldering iron to solder the three pipes separately, making sure that the tin does not fall under the circuit board.

    the second step of producing SSR: glue on the upper base plate

    the second step of producing SSR: glue on the upper base plate: clip the bottom plate into the shell, hold the shell with your left hand and the bottom plate with your right hand, and then push it down. After the shell is inserted, cut off the glue head and evenly apply glue around the shell and bottom plate. When squeezing the glue, check for any gaps around it. Glue should not be applied to the pins and thyristor.

    the first step of producing SSR: solder copper pillar for SSR PCB

    the first step: solder copper pillar for SSR PCB:  weld the small copper pillar, wait for the tin to wrap it all around, then weld the large copper pillar. The copper pillar should be placed vertically and not allowed to tilt. Tin must wrap all around the copper pillar, and tin cannot drip into it. If tin drops into the copper pillar, immediately remove it and replace it with a new one. After all four copper pillars are welded, take a look again. If there are any copper pillars that are not completely covered or tin that is not covered, then solder them with a soldering iron.

  • the third step of producing SSR: corner lamp insertion lamp
    the third step of producing SSR: corner lamp insertion lamp

    A lamp has a direction, with its positive pole having a long angle and its negative pole having a short angle. Place the lead angle in the middle of the tweezers and fold it down. After the corner is bent, start inserting the lamp with the circuit board facing upwards. Insert the lamp downwards. After inserting, use a thin 1.0 solder wire to weld the lamp corner on the circuit board. When welding, the solder joints and patches of the lamp should not be connected together. After the lamp is welded, cut off the excess corner again, and be careful not to cut the newly welded solder joints. Then start inserting the 103 capacitor, solder it on, and finally cut off the excess lead angle. When cutting, be careful not to cut into the newly welded solder joint.
