Core 6th bridge

[SounDuke]

hello everyone I wanted to know something about the 6th bridge in the Core module. Is it correct to solder FIRST the J4 pin header and the pic socket THEN to tin the edges of the isolated cable and solder them to the tin present in the two pins or not? Is there any other better method? thanks for the attention  :-X

That's the way to do it.

Bye, Moebius

p.s. I think you have thought of a alternative method (fitting /soldering IC pin /header pin same time at the PCB holes with bridge wire from the other side).. you CAN try that also ;)

[SounDuke]

yes that was  the point  ;)

Thanks Moebius

another question, just to be sure:

in the DINX4 module I've got some problems with the 4 bridges on the metal side. they are to be connected together with a pin of the shift register IC's and with the hole pad in the centre of the socket  (elements B1, B7, BC, E$29 in eagle board) right? Thanks for helping an idiot like me.

Yes, that is correct - the bridge goes from pin 15 of the chip to the hole pad in the middle of the chip. The cables must have sheathing on them between the solder points, because the bridge crosses another trace. The soldering guide on the DIN page has some good pictures:

(For the DINX4)

Another option I like to use for those bridges is this:

1. Drill that particular IC pin hole a little bigger.(big enough to fit the IC pin and the size of wire used for the bridge)

2. Put the bridge on the component side of the board (center wirepad - IC pin)

3. Put the socket over the bridge with IC pin and bridge in the same hole.

4. Apply heat on bridge pin that is in the same hole as the IC pin while applying some pressure on the socket so it melts a little grove in the socket so the IC socket can sit flat against the board.  (just don't burn yourself in the process ;D)

This both hides the bridge and saves you the trouble of messing with tiny lengths of insulation...  ;)
