Since the outside dimensions of standard flash cards still have to fit into the camera slot, thick flash cards mounted on PC boards require a very thin/weak casing which leads to cracking of SDHC cards. Hoodman resolves this issue with Hoodman RAW STEEL SDHC cards. Using CHIP ON BOARD technology which features miniaturized components so flash and circuitry are all one piece with no solder joints - miniaturization allows for thick casings that safely sandwich the internal component in a bed of waterproof epoxy. Adding the stainless steel plate to the CHIP ON BOARD technology makes RAW STEEL the best choice for photographers wanting to eliminate SDHC card breakage problems.
