1- i tried unsolder pins and resolder backwars. i wasted 2 adetpter. always their small circle around pins break. i have desolder cord and vacuum but result same. i couldnt do it properly. they are so fragile
2-i think that solder another header to pcb and solder them again to card adepter like this,
Hi,
my sugestion:
remove the pin header angled pins from the module.
Solder pins header straight to your board, fit the module to these pins on the board using the holes in the module and solder to the modules.
i tried. i wasted 2 module for this purpose. thats why i am asking. when i tried unsolder pins, these little holes around pins broke and sd card dont work. i am willing to try but first ask you. i remove solder but pins still dont go out
Hi,
When I will remove soldered pins on boards,
first I remove the plastic (black) that holds the pins with a blade or a small knife, moving the plastic a little on each pin until all of it is removed.
Then I easily desolder each pin individually.
If the pins are angled I cut the pins flush with the plastic, remove the plastic and unsold each pin individually.
Normally... a solder sucker, solder wick, and extra flux will do it. And if you're not already doing this it helps to wiggle the pin in the hole before pulling it out, and sometimes a little sideways-push with a screwdriver will break it free when there's just tiny spot still soldered.
And if you're not re-using the connector cut the pins and pull them one at a time.
If you have an adjustable soldering iron there is also low-melt solder that melts around 135 degrees C. I don't have any now, but where I used to work we used it with a surface-mount rework station. It's kind-of "magic" in-that once it melts it somehow blends-in and melts the existing solder (at a lower temperature than it usually melts).
In our setup, we used low-molt solder paste and applied it to the pins we wanted to un-solder. The board was heated from below with hot air (similar to a heat gun). The parts with low-melt solder paste would "float loose" and we could remove that part while everything else remained soldered.
The temperature was low-enough that the board didn't get damaged.... It could be cleaned "like new" with a Q-tip.
And he actually wants a compact rigid connection to allow manipulation of the SD card.
Noting the module has an angled pin header, the sequence is - cut off all the pins short above the black retainer. Carefully prise the black retainer off over the cut-off pins. Heat the solder for each pin individually and pull it out. Clean up the remaining holes with a sucker or solder wick. Once clean. place them over the pins on the new header before or after it is mounted to the host board.
Of course the right angle socket in #7 would be easier.
