Cleaning Fiber Optics
There is near zero tolerance of contamination in fiber optics. Fiber optic cable needs scrupulously clean surfaces at the glass joint to assure efficient light transmission. Any cleaner which leaves a residue will make matter worse as this will attract contaminants.
The best process for cleaning fiber optic cable is…..
Rust Free Cleaning of Component Leads & Boards
Q. Our current cleaning process has a tendency to leave spots on board and component leads. Analysis of the white spots shows oxides of tin and lead; rust-colored spots show iron oxide. FTIR analysis shows no organic content, so it’s not soap, flux, etc. I have recommended that the production people use appropriate Alconox Inc. cleaner or possibly DI water only for a very short cleaning cycle, and that they dry the boards promptly in flowing warm air. Rust is coming from tinned steel component leads. C
Custom Detergent Formulations
Q. Does Alconox, Inc. make custom detergent formulations to solve special cleaning problems?
A. Yes, Alconox, Inc. will make custom formulations to solve special cleaning problems. Of course we always try to solve cleaning problems with off the shelf cleaners, but if there are special cleaning needs that cannot be met using regular Alconox brand cleaners, then where the size of business warrants manufacturing a new formulation, we will make custom detergents.

Cleaning Semiconductor Equipment
Q. We’re getting some residue from foaming of detergent on our semiconductor handling equipment.
A. To clean semiconductor handling equipment in electronics, use a warm 3% Detergent 8 (30 mL/L) solution followed by a deionized water rinse to clean the equipment. Detergent 8 is free of any metal ion ingredients such as sodium that can dope a semiconductor.
Cleaning Electronic Parts Prior to Soldering
Q. We need to clean parts to be soldered prior to applying solder. Do you have recommendations?
A. To clean parts prior to soldering you need to consider what residues you are trying to remove from the parts and how you want to clean. For general purpose oils and residue cleaning by manual, soak or ultrasonic cleaning methods, we recommend using a warm or hot 1% Liquinox solution . . .
