This technology evolved in the 1970´s, but is still quite popular today for LED´s, TO-92´s and many classes of capacitor. Lead diameters and body case sizes vary greatly. Because of this, we like to have specific dies and tools for each particular device. This is not mandatory, however your approval would be required to proceed with existing tooling that does not exactly match the specifications. Inquire for pricing and delivery options. Our taping process follows all international standard requirements as outlined in IEC 286-2, and EIA-468 as well as your custom specifications.
