Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

Water Management in a Large Printed Circuit Board Manufacturer
April 15, 2024 | Charles Nehrig, TTM TechnologiesEstimated reading time: 2 minutes
TTM’s environmental management is grounded in its Environmental Statement and Environmental Policy, which promote measures that make for a more responsible environmental management process. Our management system helps TTM work toward minimizing its environmental footprint and increasing the sustainability of its operations. TTM monitors its environmental performance just as it monitors its operational performance, and provides the resources required to adhere to the Company’s environmental responsibilities. This enables TTM to reduce the use of natural resources required to manufacture printed circuit boards, electrical assemblies, and electrical parts and components produced at the TTM facilities.
Key to those natural resources is water. Water is a critical operational component for TTM and a critical natural resource for those who live in the communities where we operate. As a result, TTM has taken a very measured approach in the management and treatment of water and wastewater associated with our manufacturing operations. Toward this effort, TTM’s operational goals, key performance indicators (KPIs), capital plans, and sustainability goals have a component that is explicitly directed at water use reduction and water footprint reduction. TTM has undertaken improvement efforts and initiatives to reduce (or eliminate) the impact of each TTM location.
The company’s most critical environmental initiatives with respect to water management fall into the following categories:
Wastewater Treatment and System Upgrades
TTM has gradually replaced existing wastewater treatment (WWT) systems with a treatment technology that relies less on chemical precipitation and more on ion exchange. Although chemical precipitation WWT systems are robust and produce effective and compliant wastewater, and they rely heavily on chemical treatment agents to promote contaminant removal (metals), the precipitate that is produced is typically a sludge with a high moisture content and a low metal content. In the end, the standard precipitant-based WWT systems are an inefficient use of chemical treatment aids and produce a reclaimable material that requires excess energy and/or handling to reclaim the metal, oftentimes resulting in a poor return on the metal recovered, as well as the capital invested.

The Journey from Dilution to Zero Liquid Discharge
05/11/2026 | Richard Nichols, GreenSource EngineeringIf you’re familiar with the PCB industry, and a little long in the tooth like me, you may remember the cry, “The water board is here!” (or an equivalent authority). This was the signal for a frantic but regularly rehearsed exercise to turn on all the rinses. This anecdote demonstrates that in the early days of PCB production, prevailing practices revolved around a “dilution is the solution” mentality, in which manufacturers used copious amounts of water to dilute contaminants before discharging them into regulated municipal wastewater systems or natural water bodies.
