Antistatic packaging for electronic samples: Secure shipping
A practical guide to ESD materials, avoiding static damage and recommended checks before sending electronic samples by courier in Switzerland.
Quick answer
To ship electronic samples safely within Switzerland, use conductive or shielding antistatic packaging (for example metallised shielding bags), ground parts during packing, add adequate mechanical padding, and run basic ESD checks (visual inspection and simple electrical tests) before handing the parcel to the courier.
Why antistatic packaging matters
Electronic samples are vulnerable to electrostatic discharge (ESD). A single discharge can permanently damage components without visible signs. Antistatic packaging reduces that risk, protects contacts and boards, and increases the chance the sample works on arrival.
Essential materials to have on hand
Use these ESD-safe items: conductive or dissipative metallised shielding bags for assemblies, ESD-safe inner padding (conductive-surface foam), conductive foam pads for ICs, ESD tape and antistatic labels. Do not put parts in ordinary plastic bags or direct onto paper if contacts are exposed.
Step-by-step packing process
1) Work on a grounded ESD surface and wear a wrist strap. 2) Neutralise charge with ionised air if available. 3) Place the sample into a correctly sized metallised bag and seal it. 4) Cushion the bag inside a sturdy outer box to prevent movement. 5) Label the outer box with ESD and 'fragile electronics' notices.
Recommended checks before shipping
Do simple checks: visual inspection for loose parts or contamination; continuity check with a multimeter on critical paths; basic functional test if possible (power draw, boot). Inspect the bag for visible breaches. Record brief results on the delivery note.
Practical courier tips for Switzerland
Choose a robust outer box suitable for transport in a passenger car. Avoid excessive temperature and humidity swings by using dry packaging and silica gel where needed. Brief the courier that the parcel contains ESD-sensitive items and place it so it won’t be crushed or shaken.
Labelling and documentation
Mark shipments as ESD-sensitive and include a short description (part, serial number, tests performed). A checklist inside helps the recipient verify quickly. Keep test notes digitally or on paper in case of discrepancies.
Frequently asked questions
Can I use regular bubble wrap?
Regular bubble wrap gives mechanical protection but not ESD protection. Use antistatic bubble wrap or pair regular wrap with conductive bags.
Is a metallised bag enough on its own?
A metallised bag protects electrically but not mechanically. Combine it with suitable padding inside a sturdy outer box.
What tests are essential before sending?
At minimum, do a visual check and a simple functional or continuity test. Note the results for the recipient.
How should I label ESD-sensitive parcels?
Affix clear ESD labels and 'fragile electronics' marking on the outside. Include brief test info and contact details inside the package.
