Hello, I need some some Magnifier for SMD soldering so I bought these Magnifying glasses http://www.ebay.com/itm/381555608061?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT
It is good for PCB inspection but it's not for SMD soldering: for 10x magnification glasses need to be only few centimeters away from PCB and for greater magnification, distance is of course smaller so it is not possible to use it for SMD soldering. My question is, is there any cheap solution? I'm not good at optics, but smaller magnification mean larger distance, right? Is this solution http://www.aliexpress.com/item/Magn..._6&btsid=8d9303e9-107a-4a6d-b3b4-eabeec9ed4cc
