the final appearance and opera- tion in a PCB. Adhesion failure can result in delamination, cracking, and ultimately the board failure. ASTM D3359 out- lines two methods to test the adhesion of conformal coatings using either the X-cut method or a crosshatch method. Both methods use a sharp


tool to cut a pattern in the coat- ing layer followed by the applica- tion of a pressure-sensitive tape over the cut surface. The tape is then peeled back, staying close to an angle of 180°. The amount of coating removed from the sub- strate is an indicator of the adhe-

the entire conformal coating process is key to ensuring long- term reliability in coated PCBs. Insituware is dedicated to help- ing users control materials and ensure a world-class manufac- turing process. Contact: Insituware, LLC,

Creating Supply Shock Resilience through Warehouse Expansion

carts and rails, when one pallet is pulled, the one behind it rolls forward. To quickly teach forklift oper-


ators the key differences between traditional static loads and the dynamic pushback system while avoiding forklift damage or pallet rack damage, warehouse man- agers are training staff with the help of a free handbook “Pushback System Safe


Operating Procedures User Handbook” pro-


vided by Steel King. The push- back safety handbook highlights best practice procedures and illus- trates them with easy-to-under- stand graphics. However, for maximum pal-


let rack use in a minimum foot- print, along with inventory man- agement capability, a warehouse pallet flow storage system can be the answer. In a pallet flow stor- age system dynamic flow rails are inclined in a static rack structure. This allows loads placed on one end to move by gravity on rollers to the unload- ing end, with speed controllers acting as gentle brakes. As a load is removed, the loads behind it move forward automatically. Once loaded, FIFO product


rotation is automatic, and the rack eliminates labor and fork truck operation to arrange loads. Forklifts are required only for the initial and final unloading. Compared to traditional selec- tive pallet rack use, which requires multiple aisles, aisle space can be reduced by 75 per- cent and up to 100 percent more product can be stored. Realistically, not every logis-


tics firm, manufacturer, distribu- tor, or retailer has the resources to sign deals for new space before ground is broken. So, when reimagining the warehouse space, implementing one or several of the options discussed can free up significant storage space in exist- ing facilities. Contact: Steel King
