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.

When we look at the optical inspection market growth trajectory, we can see how process challenges helped create innovations. For example, solder paste inspection (SPI) has undergone a shift from 2D to 3D because the 2D inspection technologies manufacturers traditionally used to collect solder deposit images could not solve shadowing problems. Thus, companies developed 3D SPI to capture the printed solder paste height to accurately measure the total volume of paste printed. Several years later, we see the same need for surface-mounted component inspection with AOI systems.

In my role as a media representative, my perspective on IPC APEX EXPO may be a bit different from that of many attendees. Since the I-Connect007 team had the opportunity to talk to many attendees and exhibitors and listen to their stories over the course of the week, our view can be particularly wide. When I reflected on all the conversations, pieces from all throughout the week coalesced and provided a different understanding of and takeaway from the show.
