TopLine Eliminates PCB Redesign Headaches


Reading time ( words)

TopLine has launched SOT Jumper components, a low-cost way to short out (jumper) PCB circuitry without the need to redesign or spin a whole new board. TopLine SOT23 components short-out specific pins together with less than 50m milli-ohms resistance.

"SOT Jumpers are a quick and easy to replace unneeded circuits," states Martin Hart, TopLine's president. "Our SOT23 Jumpers mount on the PC board using normal SAC305 lead-free solder paste, just as regular components."

In the most common configuration, for example, Pin 1 is shorted to Pin 3; another configuration shorts Pin 2 to Pin 3. TopLine also makes a version with Pin 1, Pin 2 and Pin 3 all shorted together.

TopLine's series of SOT23 Jumpers withstand 75VDC at 100mA with 350mW power dissipation. Their operating temperature range from -65⁰C to +150⁰C. Standard and halogen free versions are available, and versions with up to 8 shorted pins are available.

Advanced Packaging Gets an Additive Upgrade

11/08/2022 | Art Wall, NextFlex
The recent approval of the CHIPS Act has reignited the U.S. semiconductor industry and shone a spotlight on the intricacies involved in chip manufacturing. As new technological innovations—such as 5G, IoT, AI, automotive and high-performance computing—come to market, they’re pushing chip manufacturing and integration capabilities. They demand more performance which leads to added complexity in an already extremely complicated process. All this requires a fundamental shift in the way that semiconductors are manufactured and integrated.
