Step 4: Diode Droptime! :-)
Parts Used:
* MBSEQ V4 Control Surface PCB from SmashTVs MIDIbox shop (SEQ CS PCB):

* 58x 1N4148 Diodes:

Description:
* In this step, we will begin to work on the SEQ control surface PCB - photo 1.
* Let´s start with the tiniest components, the diodes. Soldering from small to large parts will make the assembly process a bit easier.
* Pre-bend the diodes and drop them aligning the "marked end" of the diode with the dotted mark on the PCB (photo 2).
* To simplify the component dropping process, you can lift the PCB by a few centimeters by placing it on "spacer objects", like books.
* After dropping, you can fix the components with a bit of packaging tape on the topside of the PCB (photo 3).
* Check the diode mark alignements one more time, then turn over the board, and cut the pins (photo 4).
* Then solder, slowly counting to 116 :smile:. After you´ve reached that number, you can be certain, that you´ve soldered every connection.
* Photo 5 shows all diodes installed and soldered.
Note:
* As my friend jojjelito noted, a cool speed-up-trick with through-plated holes is to just top-solder on the "elevated pcb" - you can then skip the fix-with-tape step completely - and cut off pin remains on the backside of the PCB after soldering. Cool trick! :-)
