Switzer is heading to The Battery Show North America — and we'd love to see you there.

From October 12–15 at Huntington Place in Detroit, we'll be at Booth 5435 talking shop with the engineers actually building the next generation of battery and EV systems. Bring your toughest design questions — sourcing, tolerances, reliability under real-world conditions — we've spent our careers in exactly that space, and we're always up for digging into a hard problem.

Can't make it to Detroit, or want to grab time before the show fills up? Drop a comment and we'll get a consultation on the calendar — happy to keep the conversation going, show or no show.

See you at Booth 5435!

Shielding keeps unwanted energy contained. Internal EMI shields block noisy driver stages from interfering with sensitive low-noise circuits, while keeping outside signals out. A shield’s overall attenuation performance depends on metal conductivity, seam continuity, operating frequency, and physical aperture dimensions.

Power amplifiers also create substantial heat during high-power operation. Airflow vents and perforated screen covers allow cooling air to move through while keeping electromagnetic fields inside. Screen geometry controls this balance:

-Aperture Size: Hole diameters must stay much smaller than the signal wavelength to prevent RF energy leaks.
-Hole Patterns: Staggered pattern grids maximize open air space without dropping shielding performance.
-Material Thickness: Thicker screens work like tiny waveguides, blocking specific frequency bands more effectively.

Higher operating frequencies mean significantly shorter signal wavelengths. A vent hole pattern that blocks signals at 2 GHz might leak heavily at 28 GHz. Controlling hole sizes, slot lengths, and hole spacing keeps cooling performance high without compromising electromagnetic containment.

RF and microwave power amplifiers need more than fast semiconductors to run reliably. The metal shields, grounding clips, shims, spacers, ventilated panels, and internal heat exchangers in the housing chamber of the device perform the work of providing electrical ground connections, managing thermal flows, regulating airflow, and shielding the device from noise disturbances.

A small physical gap or minor surface bump can ruin signal cleanliness, lower shielding effectiveness, or cause system failure. Getting these internal metal parts right requires a clear understanding of how physical geometry, alloy selection, surface finishes, and manufacturing processes work together.

Photochemical machining (PCM) etches intricate features easily. Fine vent screens, complex grounding tabs, narrow circuit slots, and detailed outlines are etched simultaneously on a single sheet. If initial prototype testing reveals an RF vent hole needs to change size or a grounding tab needs repositioning, engineers simply update the digital artwork file. Revised prototype parts are produced in days, letting engineering teams test iterative revisions without long tooling delays.

Etched foil heaters operate with minimal internal heat storage. Because the resistive foil is thin—often just a few thousandths of an inch—it requires minimal energy to reach operating temperature.

Current flowing through the trace heats the foil in seconds. When current stops, heat dissipates almost instantly, delivering clear operational advantages:

-Shortened Warm-Up Times: Equipment reaches operating temperature quickly, reducing idle waiting during morning startups or batch changeovers.
-Rapid Cool-Down Cycles: Low thermal storage lets systems cool fast, protecting heat-sensitive materials and shortening multi-step processing cycles.
-Tighter Temperature Control: Fast response times let control systems adjust heat output instantly, preventing temperature overshoot and holding setpoints within narrow margins.
-Direct Surface Heating: Heat moves straight into the process rather than warming surrounding support structures.

Claims about energy efficiency require clear technical context. Low thermal mass does not create energy from less power; efficiency gains stem from operational velocity and targeted energy delivery. Less power is wasted heating heavy structural masses during startup, and cycle times decrease because equipment reaches setpoints faster.

In industrial thermal operations, thermal lag is a widespread problem. In traditional heaters, the significant mass of the heaters and heavy mounting plates means that thermal inertia is present. As energy is wasted in heating heavy mounting structures, startup, temperature changes, and temperature overshoot are delayed - with the potential for damaging the materials. Thus, thermal lag can limit the efficiency of processes requiring rapid cycling.

Etched foil heating elements eliminate this problem by reducing thermal mass. Bonding thin etched resistive circuits to insulating substrates places heat directly at the working surface. Energy passes directly to the process rather than being absorbed by the metal parts, providing quick heating, fast cooldown periods, and accurate thermal regulation.

Improving process efficiency comes down to delivering thermal energy without delay. Photochemical machining allows engineers to turn complex circuit designs into precise foil heaters that eliminate thermal lag and shorten cycle times.

The data center market is in the middle of an unprecedented buildout. AI workloads are driving power density and rack heat output to levels that traditional cooling architectures were never designed for, and operators are racing to keep pace without blowing through their power and water budgets.

That's where precision matters more than ever. Heat exchanger plates, cooling plates, and other thermal management components have to move heat with near-perfect efficiency — every micron of flow channel geometry affects how well a system cools, and how much water and energy it takes to do it.

Photochemical machining (PCM) is uniquely suited to this challenge. It etches complex, burr-free flow channels with tight tolerances and no mechanical stress on the metal, enabling thinner, more intricate designs than stamping or CNC machining allow. The result: components that transfer heat more effectively, support higher-density racks, and help data centers reduce the water and energy they consume for cooling — without sacrificing reliability.

As the industry pushes toward more sustainable, higher-performance infrastructure, manufacturing precision at the component level is becoming a real lever for efficiency at the facility level.

COMPONENT SPOTLIGHT - Flexible Heaters

What Is It?
-Manufacturers requiring localized heat for applications understand the need for dependable flexible heaters. These components can be mounted directly to equipment or other components to provide appropriate thermal transfer based on unique specifications.

There are two common types of flexible heaters: wire wound and etched foil. Etched foil heating elements have become the engineer's preferred option for the precision, efficiency, and design flexibility they bring to demanding applications. Switzer's photochemical etching process produces traces with the dimensional and resistance accuracy that wire wound elements cannot consistently match.

Common Applications:
-Military / Aerospace
-Battery / EV
-Industrial Equipment
-Food Service Equipment
-Semiconductor / Electronics Equipment
-Aviation
