Drop/mechanical shock testing is performed to determine the ability of materials or products to withstand abrupt changes in motion and suddenly applied forces. It has direct applications for any materials that will potentially be dropped or mishandled in transportation or by end consumers. Common products that are tested include printed circuit boards for cellular telephones, personal digital assistants, and handheld GPS units. However, this testing is not limited to these handheld devices. Any circuit board, product, device, or casing can be tested for reliability and durability.

There are several standards for mechanical shock testing. JEDEC Standard JESD22-B111, “Board Level Drop Test Method of Components for Handheld Electronic Products,” and JESD22-B110, “Subassembly Mechanical Shock” are common standards for electronics. Mil-Std-883 method 2002 is a standard for mechanical shock testing of microcircuits.

Mechanical shock testing provides a single shock pulse to any mounted item. At DfR Solutions, we use a Lansmont M23 shock table able to provide a maximum G force pulse of 5000Gs and a minimum pulse width of 0.25ms. The mounting table is 9in x 9in.
