The GL5506 has a significantly lower resistance for a given amount of light compared to the GL5516 AND, in dark conditions, the resistance of the GL5516 is significantly higher in resistance (as you would expect).

I’ve ordered fabrication and assembly of small PCB batches (100st) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Vervolgens, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.
I’m designing a new PCB where I have a whack of connectors that have to line up with the metalwork. There are some problematic connectors. All 4 pins are round. I want to have the holes as small as possible while allowing for good solder adhesion over the full length of the pin. I’m looking for guidance on how much clearance around the component lead I should have in order to get good solder wetting and adhesion.
I designed a PCB with an imaging sensor that is mechanically coupled to a lens assembly using four 2-56 schroeven. I’m noticing that even though the screws are holding the board tightly against the mechanical structure if I flick or lightly knock the the assembly the image “moves”. I’m hoping to get a few suggestions for ways to fix the PCB to the mechanical structure. Any suggestions for adhesives or the like? Something else?
