I broke the display corner of the cellphone. Then I got the idea to use it as viewer for SMD soldering.
The phone I used (Elephone P10) has a 13Mp camera and a HD display. Its macro focusing is good enough for the SMD use.
The stand is made of two pieces of plastic laminate ( a rigid one).
The base is 23 x 17 cm wide. A wood spacer 6 cm high is screwed to the base.
The phone stand is 17.5 x 7 cm , 3.2 cm longer than the phone to screw it to the wood spacer.
A hole is aligned to the phone camera position, eventually a lens can be added if the cellphone camera has no macro feature. A lath is added to the rear to align the phone to the camera hole.
A silicone car dashboard non-slip sticky pad has been cut to hold the phone in place during operation. You can buy it via www.ebay.com or banggood.com.
I use my desktop lamps as light sources while extra leds can be wired under the phone stand to light the target pcb.
In Android I installed the Keep Screen On Free app to keep the display on for longer time.
Good SMD soldering!
