Printed circuit boards are sensitive products: thin boards can flex, solder joints and edge connectors are delicate, and components can be knocked loose under impact. PCB export packaging has to prevent bending, protect connectors and components, and keep the board stable through multi-leg transit.

Risk Points for PCB Packs

First, board flex: a thin PCB that bends inside the carton can crack traces or lift pads. Second, component and connector impact: edge connectors, sockets, and tall components can be struck or pressed. Third, electrostatic discharge can damage sensitive chips, so packaging for electronics should consider static control. Fourth, moisture can affect boards and components on long voyages.

Foam-in-Place Protection

CosMolar places the board on a flat, supported position in the carton, with an anti-static or protective inner bag where required. AB polyurethane foam is dispensed around the board outline to hold it flat and prevent side movement. Foam is kept off tall components and connector faces, and the board edges are cushioned rather than compressed directly.

Packing Structure

Multiple boards are separated by rigid dividers or trays rather than stacked loose. The outer carton is chosen to resist stacking and side impact, and moisture protection is added for sea or humid routes. For populated boards with heavy or tall parts, the pack is validated with a drop test before bulk rollout.

CosMolar Service

CosMolar chooses foam density by board weight and shipping route and supports the pack with free sample testing. Equipment carries a one-year warranty, with 4-hour phone response and 24-hour on-site service in the Pearl River Delta and 48-hour response nationwide.
