Eurocard DIN41612 3U Prototyping board PCB card 160 x 100mm

Introduction

I have originally designed this PCB for few of my project, but this turn out so well that I have now posted all schematic, gerber files and documentation to fellow enthusiast such as yourself. Perhaps (and I hope) content in this obscured corner of interwebs will inspire you to start your own projects.

Eurocard is a European standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis sub-rack which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf. At the spine of each card is one or more connectors which plug into mating connectors on a backplane that closes the rear of the chassis.

Eurocards system in generally is enormously versatile for all kinds of projects thanks to standardized mechanical dimensions and quality connectors. Eurocards PCB's come in many sizes (wikipedia article). This is single height most common size 3U single height x 160mm card. I have also designed 3U Prototyping board PCB card 220 x 100mm if you require bigger prototype card. You can use these card in industry standard DIN subrack or Eurorack. Card will fit nicely in PCB guide rails with front panel Eurorack if you wish to use one.

Card has been designed to be very versatile and you can fit DIN connectors each side if you wish or DIN connector / Eurorack front panel configuration.
Card can also be stacked with others (use standard 2.5mm / 3.00m diameter PCB spacer and simply just prototype your project on them.
These boards look absolutely gorgeous in standard green solder mask if you going for that standard industrial look. I can advise you where to buy connector and front panel holder.

Assembly instructions and notes

■ Gerber files contain " JLCJLCJLCJLC" to silk layer. You can specify a location of the order number, select the "Specify a location" option when you place an order. Only if you order via JLCPCB
■ Fit Female and Male DIN 41612 96pin 3x32pin right angle connector or alternatives you wish to use
■ Use M2.5 screws and nuts to hold DIN connectors in place, thse don't need to be fitted to achieve strong mechanical connection however
■ Use a temperature-controlled soldering station and quality solder. Take care not to leave solder bridges as any short circuit will most likely lead to failures
■ All jokes apart; when using a riser extender test card, it is important to exercise caution when working with sensitive electronic components. Users should ensure that the device is turned off before inserting or removing any cards under test. This precautionary measure can help prevent damage to the components and the system.

Versions and revisions

This section lists the project version and revision history.

v1.5

■ Silkscreen update, amended prototype holes, updated pcb files in KiCAD

v1.41

■ Silkscreen update, added numbering next to DIN41612 3x32pin connector header on both sides of PCB for easier navigation. This should result faster navigation when following some kind of schematic, ie. faster to find exact row and column.

v1.4

■ Fixed hole position so that DIN connector can be attached to both ends.
■ Various silkscreen updates, hole matrix text can be read from both sides or upside down.
■ Corners of PCB back to sharp edges. Last page update: 16 June 2023
