When the size of the printed board is not suitable, we can change the size by trimming, and trimming is relatively simple. Although this operation is simple, it still needs to be carried out under the premise of correct operation. Let's introduce how its trimming should be operated?

1. Trimming is generally achieved before the steel plate is positioned. Of course, the same is true after installation, but there needs to be enough clearance at the top of the plate.

2. Place the trimming tool on the chassis of the printed board, hold the terminals of the steel plate with the tool, and fold the chassis up. When the plate is used on a roof with a slope of less than 1/5, bend the bottom end of the chassis at the lower end slightly downward to ensure that rainwater is drained along the color steel dock. At the same time, the downward folding operation must be carried out after the steel plate is fixed, otherwise it will hinder this operation.

3. When folding down the side end of the steel plate, properly open the opening of the pry tool, clip the tool on the chassis end, and refer to the referral as much as possible. When the tool is close to the end of the chassis, shake the handle about 200 ° to form a downward fold at the end of the printed plate. In this way, the trimming of the steel plate is complete.

The above is some introduction to the trimming operation. The size of the printed board can be changed by trimming, but after trimming, the trimmed burrs must be polished in time to avoid burrs.
