Hi, Im having trouble soldering those ever so more itsy bitsy and teeny weeny components, especialy those chip scale packages wich dont even have any reference marks for the conections when viewed from the top.
I have a X20 pocket microscope but is handheld so only good for looking for shorts and and reading the SMD codes (i have good close up eyesight - i can just about read a 0603 code directly)
Ive done 2 of these packages so far using gouge technique to make the pcb, and one with dead bug technique, ive found adapting a scalpel to take two blades cuts 2 lines 0.5 mmm apart wich is just the right pitch. its tricky but I need to be able to see it a bit better to get the lines exactly on pitch.
But trying to line up the packages when you cant see where the leads are underneath is a bit of a nightmare, So whats the most convenient and cost effective magnifying device ?
bench microscope ? .. seem to be quite expensive for a good one, cheap ones seem a bit to cheap and I havnt found much inbetween yet, and image would need to be correct way up Ive even thought a usb microscope camera wich seem surprisingly cheap might do, or just an eye glass ? or binocolar magnifiying glasses ? or would those round flourescent desk lamps with large magnifiying glass in the middle do quite well ?
