Chosen Solution
This is a Fluke VoltAlert 1AC-A II. I have to extract the PCB from the chassis of the same in order to re-heat some components. The circuit moves, but it stops even 1 mm. I tried to see where the block was, but I could not see it. Is there anyone who has already extracted the circuit and knows how? The acid output from the batteries has corroded some welds that have to be redone, but to access them I have to be able to pull the printed circuit strip out of the wrapper that contains it. I need to know where to unlock to allow the exit as it flows though for a very short ride (less than 1 mm)
I was able to extract the PCB by digging a small hole right next to the button (I used Blake’s picture as reference). Just dig until you can see the small metal clip, push it down with a small tool and you should be able to slide the PCB right out of its case easily. Actualización (07/05/19)
Yes. I used a small drill, but was also considering using a soldering iron tip to melt the plastic and get to the clip. Whatever tool that can go through plastic should do the trick, just make sure you can reach the metal clip to push it.
I sacrificed my fluke to the cause, it didn’t make it. However I used unconventional methods, but I figured it out. So if you take the button off with a pair of tweezers there is a clip right behind it towards the butt of the pen. You “should” be able to just stick something in there to push it down and it can slide right out.
Hola, mi probador de voltaje (Fluke 1ac A Ii Voltalert) estuvo expuesto a mucha humedad y se llenó de sarro, por lo que tenia que sacar el PCB para limpiarlo. Estuve cerca de 40 minutos intentando encontrar la forma de sacarlo y nada funcionaba. Gracias a la imagen de referencia de @ivanm y la de @billingsaur pude hacer el orificio en el lugar correcto, adjunto la imagen para que le sirva a alguien mas.
