Hello guys. I describe my problem. Have bought a multipac series 1U rack enclosure. My intention was to move two boards of the supergreen preamp, and put one AD there, heaphones amp, and guitar preamp.
The problem is that I didn´t consider ok the internal height of the multipac enclosure before buying, and I thought I could put all the boards there without problem. But the internal height is around 35-36mm.
The problem starts with supergreen board, (already built that was working in another box). It has two Wima caps of 30-31mm o height. The board is 2mm thinkg aprox, and the soldering tips that are around 1-2mm. The result ir nearly 35mm, so the board fits inside but without gap under the board. I have thought about using insulation tape to cover the bottom of the enclosure to avoid shorcut with the board bottom, but a question appear to my mind. A cap consist in to surfaces separated by a insulation surface, so maybe can occur that if put the board this way? a cap between the enclosure bottom and the board? How much space should I need to have between the board and the case to be sure that will have no problems?
Another solution, I have thought about, was to change the position of the Wima caps. If I put then in horizontal position, they would have 20mm of height, so win 10mm, and could use a standard 10mm stand. Would be any problem with the position of the Wima caps this way over the board? I have space, only two resistors I could solder in the bottom of the board.
I have another two electrolytic caps too big, that i should need to put in horizontal. Even those would no need to be just placed over the board surface because they are thin.
I´m sure many of you have had this type of problem sometime. So hope you have help me. ???
