Selective soldering in an optimized nitrogen atmosphere

Nov 14, 2023 | Gerjan Diepstraten

In PCB circuit assemblies the trend is moving to more SMD components with finer pitch connections. The majority of the assemblies still have a small amount of through hole (THT) components. Some of them can't withstand high reflow temperatures, while others are there because of their mechanical robustness. In automotive applications these THT components are also present. Many products for cars, including steering units, radio and navigation, and air compressors also use THT technology to connect board-to-board, PCB's to metal shields or housings out of plastic or even aluminium. This is not a simple 2D plain soldering technology, as it requires handling, efficient thermal heating and handling of heavy (up to 10 kg) parts. Soldering technology becomes more 3D where connections have to be made on different levels. For this technology robots using solder wire fail because of the spattering of the flux in the wires and the long cycle time. In wave soldering using pallets the wave height is limited and pin in paste reflow is only a 2D application with space limitations....

Dispensing: A Robust Process Solution for Shield Edge Interconnect

Nov 06, 2023 | Rajiv L. Iyer and Michael L. Martel

A new process has been developed for RF shielding on compact electronic communications devices using automated solder paste dispensing. The process is known as Shield Edge Interconnect (SEI). SEI designs enable parts to be processed though underfill before placing of the RF shield and allows more complete use of valuable PCB real estate to achieve reduced form factor requirements and/or for added components on products such as smartphones and tablets. The reduced form factor creates challenges for the assembly of those devices. This process, enabled by Speedline dispensing technology, relies on extremely accurate dispensing of solder paste on copper traces located along the outer edge of the PCB. The result is a robust process solution for SEI in which proprietary closed loop dispenser, pump, vision, and software technologies enable a high volume manufacturing (HVM) process....

Design and Fabrication of a PCB MEMS Module with Integrated Switches and Sensor Suite

Oct 09, 2023 | David Boteler, Nicholas Marsiglia, Ching-Yi Lin, Li-Anne Liew, Y.C. Lee

We demonstrate the feasibility of integrating Kapton-based MEMS capacitive switches and a sensor suite onto a printed circuit board with minimal impact to existing manufacturing processes. Copper-cladded Kapton laminates were bonded onto rigid PCB substrates with a BCB film spacer. The Kapton was patterned using reactive ion etching to produce MEMS structures such as suspended membranes and flexures. Atomic layer deposited alumina coatings were applied as dielectric layers for the capacitive switches and tilt sensors/accelerometers. The copper cladding was also patterned by etching to function as electrical leads, resistors, and capacitive electrodes. In this way, MEMS switches, tilt/acceleration sensors, temperature sensors, humidity sensors, and vacuum/pressure sensors, were all fabricated monolithically onto a PCB in a single module in the same fabrication process. We describe the fabrication process and demonstrate the functionality of the various sensors and switches in the module.

Analysis of the Mechanical Behavior, Microstructure, and Reliability of Mixed Formulation Solder Joints

Sep 26, 2023 | Yifei Zhang, Kanth Kurumaddali, Jeffrey C. Suhling, Pradeep Lall, Michael J. Bozack

The transition from tin-lead to lead free soldering in the electronics manufacturing industry has been in progress for the past 10 years. In the interim period before lead free assemblies are uniformly accepted, mixed formulation solder joints are becoming commonplace in electronic assemblies. For example, area array components (BGA/CSP) are frequently available only with lead free Sn-Ag-Cu (SAC) solder balls. Such parts are often assembled to printed circuit boards using traditional 63Sn-37Pb solder paste. The resulting solder joints contain unusual quaternary alloys of Sn, Ag, Cu, and Pb. In addition, the alloy composition can vary across the solder joint based on the paste to ball solder volumes and the reflow profile utilized. The mechanical and physical properties of such Sn-Ag-Cu-Pb alloys have not been explored extensively in the literature. In addition, the reliability of mixed formulation solder joints is poorly understood....
