Hardware description: Radio module slot pins protector

Author El.Szaman

Problem

Many users have problem with break off pins from radio communication slot. You can check this, because damaged pin is pushed into transmitter (it much lower than others). It can be caused by too much force or carelessness during module insertion. We can secure pins by using epoxy resin, or other popular 2-parts glues like POXIPOL. Bending pin is much easier to repair than repairing PCB paths... Most common problems are ripped of pins and paths from PCB. It can be of course fixed, but it takes more effort than creating this protection.

Solution

In this example I used standard epoxy. Before applying you need necessary to degrease PCB and not touch it with fingers afterwards. If we want to use half-liquid epoxy, then You need to protect field which we want to secure (for example by using adhesive tape). But remember to remove this tape before epoxy get hard. It easier to prepare epoxy on paper, then use spatula to move required amount on PCB. Do not throw away that paper with epoxy yet, because it can be used for checking when You need to remove protecting tape. Before You do this mod, answer Yourself if you need to use this transmitter with any JR radio module! That modules requere additional +6V supply on pin which is marked with red arrow. If yes, then first apply +6V hack, then use epoxy to protect pins.

UWAGA!!! Do tej modyfikacji Rafit napisał WAŻNĄ poprawkę: "Zanim to zrobimy dobrze jest odpowiedzieć sobie na jedno pytanie - czy KIEDYKOLWIEK zamierzamy używać modułów innych producentów, np oryginalnych JR. Jeżeli tak to należy dokonać jeszcze przeróbki złącza. Złącze zainstalowane w Turnigy 9X nie jest w pełni zgodne ze standardem. Nie posiada napięcia 6V na 4 pinie (2 od dołu na dolnym zdjęciu). Może warto rozważyć najpierw dokonanie odpowiedniej modyfikacji, ponieważ po zalaniu żywicą będzie to bardzo trudne. Modyfikacja polega na odcięciu połączenia pomiędzy masą a pinem nr 4 i instalacji dodatkowego stabilizatora 6V."

Implementation

Prepared "operative field" has been flooded with epoxy:


Pins secured that way are hard to push into. Red arrow is pointing PIN for +6V hack:
