When designing electronic circuits, often it’s necessary to have a proper enclosure for the project, to protect the circuit board and components, and for aesthetic reasons. There are several options to choose from. For example, if this is a one-off project, you can pick an off-the-shelf enclosure, make custom cutouts to fit the PCB and […]

While it has worked reasonably well, recently it has started showing some signs of aging. First of all, the total reflow time is quite long, about 15-16 minutes. This is really […]

As I am getting more experienced with the TM-240A pick and place machine (in the following I will call it the PNP machine, as in PNP transistors 🙂 ), I’ve been thinking of ways to improve productivity. One obvious way is to panelize PCBs, meaning to assemble multiple copies of the PCB onto the same […]
