12d. Soldering a pin header

This is a guide to enable you to solder the 10 pin Header onto the Motorola Surfboard Series Modems


1) Remove the case and you can see in this first picture of the surfboard where your 10 pin header goes, whether it is a solder less type or not.

For the header to sit correctly you must remove the lid off the chip and some of the surrounding metal.

There's no need to worry about replacing the lid there's no use for it.

NOTE: Be very careful when doing this, as if you just try pulling it off, it may damage the circuit board. The best way to do this is to use a heavy duty wire cutter and cut though the metal in the 2 places marked in red above. Again be careful not to damage any components around the area.


2) Now with a pair of pliers carefully twist the metal between the 2 cut points back and forth until it becomes loose then it should easily come off.








3) Once this has been done, and all sharp edges tucked away you can place your header onto the surfboard, but it must be placed in the correct way, as shown, if you are going to flash the modem with the non IC version of the Blackcat lead. This must be followed correctly otherwise you will not get the flash to take and can screw your modem up.

 Warning if you intend to use the buffered version of the blackcat the cut out shuold face the other way around

4) Once in place you can turn the modem over so we can start to solder the header onto the surfboard (As you can see in the picture there's a lot of Glaze on the board, this is just because the modem has had the header removed and replaced for the purpose of this tutorial)


5) The next thing is to plug your soldering iron in and when hot enough, tin the end with some solder. This will increase the flow when you come round to solder the header onto the board. Theirs no need to pile a load of solder onto the header and use braid to clean off you can do this quite easily by soldering each pin one by one to the board if you have a steady hand.



The best thing to do first off is to have a play around with some copper wire just to get the feel of how much solder you need to put onto your iron and then crack on, you don't need to be a master (I am no master, believe me)


6) That's it, you're done! Just make sure that there are no short circuits. It's always a good idea to clean off any flux with an anti-static brush & a special electrical spray (DO NOT use normal cleaners as they may damage the board)
