Originally posted by ismaelg The melting point of the solder was only a few degrees lower than the damaging burning temp of some components so it was some sort of an art to do manually.
In the late 1970's a tech declined repair on my CB radio because he claimed it had dual sided pc boards.
Now circuit boards can have multiple layers. Those must be lots of fun to work on!
Modern electronic camera bodies use flexible circuit boards with surface mounted components;
I destroyed several of these by burning holes through a few even at the solder safe points.
Given inevitable electronic component failure without spare complete circuit boards
unlike mechanical models these cameras have a finite lifespan.
