How small a hole can you view. Thanks Steve Kelly -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Franklin D Asbell Sent: Tuesday, September 05, 2000 1:26 PM To: [log in to unmask] Subject: Re: [TN] Non-destructive Thru-hole Inspection Dave, A device we use that is quick and easy is a PCB through hole eyepiece (kind of ironic, yes...~grin~) Sometimes called a prism eyepiece. Any supplier of optical devices for electronics should be able to direct you to a source. This device uses a prism lens that splits the through hole into 9 images each a an oblique angle for viewing the holl wall. It's a real quick way to confirm hole wall quality.
