Privacy Policy Update
Click here to learn about the new Privacy Policy updates from Practical Components.The new B-52 Rev. B board is the newest revision of the existing B-52 CRET board. Practical will continue to offer the B-52 board on a transitional basis over the next year. The B-52 Rev. B board continues to provide a platform for the electronic assembly industry to evaluate the cleanliness of the assembly process. Both Rev. A and Rev. B boards have the same board thickness (.062) and use the same components. On the Rev. B the copper designators have been moved out. The Rev. B board width has increased and the manufacturing rails have been removed. The non-plated holes were revised to accommodate the alignment pins of the connectors, in addition the diameter of through holes were reduced for better solderability of the through hole connectors. The ground plane was changed from solid copper to copper mesh. These changes should have a positive effect both on assembly and evaluation results.
Items to note are the B-52 Rev. B is available with just the SIR coupon. Information regarding this option is available by calling Practical Components at 714-252-0010. In addition, it is recommended that customers use test boards from their current or potential board supplier. Test boards can also be customized to fit specific customer needs.
