My understanding is that the lotion is considered non-contaminating and solder-safe; free of chemicals that may adversely affect solderability or cause corrosion of electronic components if it passes Flux Induced Corrosion (Copper Mirror Method) test defined in IPC-TM-650 Test Methods Manual Gene Felder [log in to unmask] -----Original Message----- From: Phil Nutting [SMTP:[log in to unmask]] Sent: Friday, March 07, 2003 2:00 PM To: [log in to unmask] Subject: Re: [TN] Finger cots/Gloves/nothing? << File: ATT00009.htm >> What happens when we use "IC Lotion" on our hands and then handle the boards or components (thru-hole)?

Even with clean bare hands, some people's skins have more oil than others, and this can deposit on the board. I have seen some fingerprints that did not allow for proper adhesion of coating. I have also seen how contamination on a glove was transferred to several boards, and caused issues with coating quality. We use gloves and cots, but either way you go, the biggest key will be how well your personnel keep their hands clean, or how often they change their cots or gloves.

Advice requested, I'm sure this topic has been broached before, but I would like to solicit your opinions on the subject of using fingercots or gloves verses using bare hands when handling components or PCB's before soldering or conformal coating (IPC Class II). I tried to do a TechNet search on this, but it failed to go through for some reason. I am of the opinion that careful handling of components or PCB's by their non-soldering surfaces with clean bare hands is the way to go. Of course, it is up to manufacturing personnel to keep their hands in a clean condition. From what I have seen, gloves just tend to soak up and disperse multiple contaminants on soldering surfaces and they give personnel a false sense of security. Any thoughts? Thanks in advance for the advice.
