Coastal Care

By Bertus Wessels, Mr

A short SMT floor note on coastal care where salt air, moisture and storage discipline affect boards and parts.

Near the coast, electronics handling needs more than the usual floor routine. Coastal Care is our note on protecting boards, reels, paste and metal surfaces from salt air, moisture and storage lapses that show up later at print, placement or rework.

Coastal handling notes need direct wording because salt residue and damp storage show up later as solderability faults, tarnished leads and warped packaging. Our Coastal Care page points to checks that matter in Durban, Gqeberha and Cape Town stock rooms where reels, bare boards and opened paste do not behave like inland stock.

Salt-air points to record

• Coastal site and storage area named
• Photo of reel, board or oxidised surface added
• MSL status or bake record referenced clearly
• Name and production role written as used on site

Compare the linked machine and process material that touches storage, placement and heating. Coastal issues rarely stay in one station because moisture picked up in stores can surface at print, reflow or rework. Read the journal item with the equipment pages when you need the full chain.

Where Coastal Care matters during a real SA factory week

Coastal Care focuses on what salt air and moisture do to boards, reels and stored parts near the coast. It is a practical note for teams tightening storage discipline before corrosion and handling issues start showing on the line. Keep it close if your stock moves between inland and coastal sites.

Start with the board finish, package type and where the material was stored before it reached the line. ENIG pads, exposed metal tooling and moisture-sensitive devices react differently when stock moves between Johannesburg and the coast, especially after a weekend in humid air. Teams in Durban, Cape Town and smaller coastal plants usually need tighter bag sealing, desiccant checks and rack discipline than inland sites.

Take the first photo while packaging labels, humidity cards and reel condition are still untouched. A note clipped to the stock bin helps operators see whether the material came from a dry cabinet, a sealed moisture barrier bag or an open shelf near dispatch. That simple record can explain later printing defects, poor wetting or unexpected touch-up work.

SA conditions that change storage

South African electronics stock often travels between inland warehousing and coastal assembly, which changes how moisture exposure should be logged. Material can leave Gauteng dry and reach a KZN or Western Cape site needing different handling once bags are opened. Older industrial units, shared stores and courier staging areas also affect how long reels or boards sit in uncontrolled air.

Near the coast, chloride-laden air can mark exposed metal, feeder parts and board edges faster than many teams expect. Inland dust creates a different maintenance pattern, but coastal humidity is the bigger risk for MSL parts, paper reels and opened solder paste containers. During power interruptions, cabinet access and stock movement should still be recorded so exposure time does not get guessed later.
