![]() ![]() The key to this method is the engineered polyimide and other polymer-based carrier ("preform") which holds the solder balls in place. This BGA reballing process was developed primarily with the speed of attachment and simplicity in mind. It does not store any personal data.EZREball™The solder EZReball™ preform technique (IPC 7711/21 5.7.5.) used for reballing area array devices is one of the methods used at BEST for the attachment of solder balls.

Precision stampings are a hallmark of Coining. Coining has made parts as small as 100µm (0.004″) with a tolerance of ☑2.5µm (0.0005″). They have a wealth of experience manufacturing parts with overall tolerances of ☑2.5µm (0.0005″) to ☑.25µm (0.005″) and thickness tolerances of ☒.3µm (0.0001″) to ☑2.5µm (0.0005″). Coining also uses progressive dies to create a variety of 3 dimensional configurations and uses EDM-built tools to provide extraordinary precision and variety to the geometries of their parts. Essentially, if a shape is possible, Coining can make it, quickly, precisely and efficiently.Ĭoining utilises its in-house tooling department to review, design and build tooling to customer specifications. This allows for cost-effective R&D, followed by building a tool to the correct size once production is about to commence.Ĭoining’s fabrication capability is limited only by the physical constraints of the material that is being made. Other alloys are also available, which are used to connect electronic circuitry, package electronic circuitry, dissipate heat, or provide an interface for an electronic connection.įor R&D prototype volumes, Coining supplies solder ribbon to the required width and thickness so that the customer can cut the ribbon into the various shapes that may be required in the early stages of a program, when exact die / component sizes may be unknown. gold tin, gold germanium, gold silicon, etc. Coining manufactures high quality preforms in all shapes and sizes, including gold-based eutectic die attach solder preforms, e.g. ![]()
