And I am comfortable with the idea that a 'properly' designed 'properly' applied sheet of material (such as glass) can be 'safely' held by adhesive for the design life of a building when all assumptions turn out to be valid.But, I also know of glass panes that have "just fallen off" buildings and here (New Zealand) one man fell to his death when he leaned against an adhesive retained full floor height window-pane - which then fell off :-(.People "designing" fastening systems with lesser resources and capabilities can in general be much more sure of "getting it right" with mechanical fasteners than with adhesives.I have been involved with the use of adhesive fastening on maybe 500,000 products made in a number of (Chinese) factories over a number of years. - Permabond is an ISO QMS certified company - Digital Solutions Provided by Rebel Interactive Group Permabond’s range of adhesives for electronic applications has been carefully selected to offer the user maximum performance in a number of ways.

Conformal coatings probably provided some slight additional protection too.Small SMDs probably don't need mechanical fixing, since they hardly exert a force on the soldering thanks to their low weight, often milligrams. A wide variety of glue for electronic component options are available to you, such as double components adhesives, other adhesives, and volatile solvent adhesives. As I said above: (1) Note that the silicone rubber used MUST be neutral cure where electronics or corrosion sensitive components are used.

Expect 20+ year lifetimes.If initial mechanical location is required, hot-glue (hot melt glue) For long term survivability, anything that needs more mechanical strength than its solder connections provide An excellent combination where mechanical retention or location using the adhesive is required is to use a "dab" of hotmelt glue to hold things in place initially and then use silicone rubber as the long term binding and antivibration agent.As well as their excellent low modulus and long life, SR's make excellent waterproofing and sealing agents.

Ventilate well if using kgs at a time :-).Dow Corning make a wide range of SRs that are available in most countries and which have extensive technical data available. Thanks, Pravardhan U.S@dhanu85 You need to decide for yourself from what is available to you.

Electronics design engineers regularly face the dual challenge of tracking down the correct adhesive for their application, while also focusing on aspects such as keeping material costs low. If you want to lead off with "everything should use nuts and bolts", I'd point you to 3M whose adhesives hold the surface of the world's tallest building on. If you take bothe the original question and what I've written as a whole it seems preasonably OK as is. Solvents tend to be used which may have adverse effects. Latex and contact glues are low modulus and can be useful.
