Reducing Soldering Cycle Times for Next-Gen Power Supplies

Siemens Industrial Manufacturing, Engineering and Applications (SIMEA) planned to introduce a new line of miniature power supplies, but the complexity of the design required soldering cycle times that stretched the company's machines beyond their limits. Partnering with Ersa, SIMEA ...

Testing Cables and Connectors in Medical Equipment

A demand for higher-capacity devices within the same external envelope is driving electrical design toward increasingly compact solutions, especially in medical electronics. This includes combining signal and power lines within a single connector and reducing the pitch of board connectors ...

Voiding in SMT Assembly: Causes and Solutions

Solder voiding is a maddening problem. It often occurs within the solder joints of BGAs and larger SMT pads where solder volume is higher than typical joints, or where the solder is sandwiched between structures. Voids are often caused by flux trapped within the joint, as well as other ...

What Does Lean Production Planning Really Look Like?

The traditional lean approach to manufacturing is to ensure that all production processes run at maximum capability and that resources are available to meet the best productivity metrics. However, benefits from this lean practice can only be completely seen when production throughput ...

Zero-Defect Soldering: Quality Management Based on Quality Assurance

The ultimate goal of manufacturing is to reach zero defects. Manual rework is time-consuming and expensive, personnel must be trained and assemblies often go through production a second time. These entire boards are exposed to the thermal load again, not only the faulty solder connections ...

Evaluate Soldering in a Nitrogen Atmosphere

Soldering in a nitrogen atmosphere can improve solder joint quality and manufacturing yields. Performing circuit assembly in an inert gas atmosphere offers many benefits, especially for lead-free products assembled under high process temperatures, where oxidation and contamination of ...

JTAG/Boundary Scan Makes Dependable Test Connections

Shrinking, densely populated printed-circuit boards (PCBs) and electronic assemblies make efficient electronic testing of electronic products ever more challenging. Compact assemblies and components create serious issues in terms of mechanical test-point access when it is time to develop ...

Methodology Helps Detect Counterfeit Components

Counterfeit components are now a real concern in electronics assembly, not just for expensive items but more and more for lower-costing components. Many involved in PCB assembly will admit to having received counterfeit components in the past, and/or know someone who has. A counterfeit ...

Optimizing OEE: A Key to Successful Onshoring

Electronics manufacturing production is returning to American shores. Moving production to China or other offshore locations is no longer as attractive now as it was a decade earlier, with labor rates climbing and manufacturers gaining a clearer understanding of hidden costs connected ...

Setting Test Straight With A Novel Fixture Solution

In-circuit-test (ICT) fixtures have been a cornerstone of electrical testing for the past several decades. However, there have been few, if any, significant advances in this field over the past 20 years. ICT fixtures have steadily become more complex, which in turn increases the turnaround ...

Understencil Wipe Cleaning Yields Improvements

Understencil wiping has gained growing interest over the last several years. Due to the use of ever smaller components and increasingly dense interconnections in the design of printed-circuit boards (PCBs), stencil cleanliness is more important than ever, both inside the aperture wall ...

Why Automatic Thermal Profiling Outperforms Manual Approaches

Electronics manufacturers are constantly seeking improved performance for reduced cost. As part of electronic manufacturing, one of the last manual tasks to make the transition to automation is thermal profiling. Yet, the technology for real-time thermal automatic profiling (AP) certainly ...
