As shown in the figure above, if you want to insert the PCB vertically into the spring and solder it, you can design the PCB as shown below, place the pads, and make grooves in the mechanical layer. This is theoretically possible.

Is there any standard way to do it, or a better way?

In addition, this board needs to be designed with 4 layers, and the pads need to be connected on the top, bottom, and two middle layers. There is only the middle option in the pad properties. Does it mean that both middle layers are connected?

Are you talking about the one in your picture? This is a full-through hole, unless you make a special setting to set it to buried hole form, directly placed is generally a via form, that is, each layer is connected

Metallized slotting?

On the Mechanical 1 level,

You can try this, but the key is that this slot is not fully metallized. The upper part of the copper shrapnel below needs to be welded, and the lower part is elastic and cannot be welded. Metallized slots cannot be opened like this, right?

Are you referring to the PCB screenshot? My approach is theoretically feasible.

The question is not clear, I understand it very well.

The PCB is inserted into the spring and welded vertically. How to weld without metallization? Do you consider the power size, welding convenience, maintenance convenience, etc.

Have you considered designing it into a dedicated connection socket pin form?

The board in my hand represents the board that needs to be designed. In the future, there will be 14 relays on it. The one with a row of copper sheets at the bottom is a special socket installed on the panel. In order to facilitate disassembly, the board and the socket must be welded together, and then passed through the panel hole to fix. The current and strength of the inter-board connector are not enough, and the board adapter cannot be used, so this vertical plug-in method was thought of. The board needs to be inserted to the bottom, close to the black base as a support, and the solder pad needs to go higher.

It means that there is still a fixed effect, which requires strength.

Consider whether it is easy to weld, whether there is a large current, etc.

qwqwqw2088 posted on 2021-3-17 09:51 It means that it also has a fixed function. The strength required should take into account whether it is easy to weld, whether there is a large current, etc.

Yes, the board needs to be fixed on it, and the current will reach 8A for 10 minutes.

Considering the strength, additional support must be designed. Depending on the number of signal lines and high current lines, you can find a suitable inter-board connector. By the way, one direction: Among the products I repair here, there is a connection method that only uses L-shaped pins, which are directly welded on both sides on two boards and then supported by structural parts.

Thank you for providing ideas. I am embarrassed about this. The board is full of relays. After welding, it needs to pass through the 40*86 panel opening. Now the design is ready. The direction of the teeth is 86, the total height is 100, and the welding with the seat is done by your own method. Try it first.
