88 DESIGN007 MAGAZINE I SEPTEMBER 2021 Billions of dollars are spent yearly on CAD and CAM software to produce complex PCB designs and fabricate PCBs. The final technical manu- facturing decisions generally are made by one person for each design. This is the PCB fabricator product engineer. But I don't think most design, procurement, or NPI teams understand how critical this person is to the data transfer success and liability protection. TOP TEN Fresh PCB Concepts: Does the Assembly Process Damage a PCB? (Part 2—Time to Delamination) In Part 1 of this series, published back in April, I commented upon the effect the assembly process has upon a printed circuit board. There is another gauge that can be used to help a designer or contract manu- facturer understand this point and that is the time to delamination test. These are referred to as either the T260 or T288 tests. DFM 101: PCB Controlled Impedance One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer's perspective) and the design decisions that will impact product reliability. Dana on Data: The Critical Importance of the Fab Product Engineer The Digital Layout: Say What You Do—Do What You Say In this month's column, Kelly Dack provides answers to some common questions about joining an electronics industry organization. PCEA Chairman Steph Chavez conveys his excitement and anticipation of events to come and how the PCEA will be involved. David Duross Dana Korf EDITOR'S PICKS
