Medical Device Manufacturing: Designing for X-ray Inspection

Nov 20, 2023 | Gil Zweig

When x-ray inspection is used as part of a quality assurance program for any assembled device, steps must be taken early in the design stage to anticipate the use of x-ray inspection later in the development and production processes. This is a lesson that electronic assembly manufacturers learned years ago, and that medical device manufacturers are also discovering. There are several steps involved in learning how to interpret x-ray images, and how to design for x-ray inspection. First, manufacturers need to understand the nature of the x-ray shadow and its modalities; then they need to see how medical device developers and manufacturers are using x-ray inspection; finally, they need to consider taking measures early in the design process to ensure a clear, accurate image when the assembled device undergoes x-ray inspection....

Enhanced X-Ray Inspection of Solder Joints in SMT Electronics Production using Convolutional Neural Networks

Nov 20, 2023 | Konstantin Schmidt, Nils Thielen, Christian Voigt, Reinhardt Seidel, Jörg Franke, Yannik Milde, Jochen Bönig and Gunter Beitinger

The electronics production is prone to a multitude of possible failures along the production process. Therefore, the manufacturing process of surface-mounted electronics devices (SMD) includes visual quality inspection processes for defect detection. The detection of certain error patterns like solder voids and head in pillow defects require radioscopic inspection. These high-end inspection machines, like the X-ray inspection, rely on static checking routines, programmed manually by the expert user of the machine, to verify the quality. The utilization of the implicit knowledge of domain expert(s), based on soldering guidelines, allows the evaluation of the quality. The distinctive dependence on the individual qualification significantly influences false call rates of the inbuilt computer vision routines. In this contribution, we present a novel framework for the automatic solder joint classification based on Convolutional Neural Networks (CNN), flexibly reclassifying insufficient X-ray inspection results. We utilize existing deep learning network architectures for a region of interest detection on 2D grayscale images. The comparison with product-related meta-data ensures the presence of relevant areas and results in a subsequent classification based on a CNN. Subsequent data augmentation ensures sufficient input features. The results indicate a significant reduction of the false call rate compared to commercial X-ray machines, combined with reduced product-related optimization iterations....

MODERN 2D / 3D X-RAY INSPECTION -- EMPHASIS ON BGA, QFN, 3D PACKAGES, AND COUNTERFEIT COMPONENTS

Nov 20, 2023 | Evstatin Krastev and David Bernard

With PCB complexity and density increasing and also wider use of 3D devices, tougher requirements are now imposed on device inspection both during original manufacture and at their subsequent processing onto printed circuit boards. More complicated and dense packages have more opportunities to exhibit defects both internal to the package as well as to the PCB. As components increase in complexity their cost increases, making counterfeiting them a potentially lucrative business for unscrupulous individuals and organizations....

Understanding The Crucial Role Of Dust Collectors In PCB Depaneling Machines

Nov 20, 2023 | I.C.T

Understanding The Crucial Role Of Dust Collectors In PCB Depaneling Machines Precision is paramount in PCB manufacturing, but it must go hand in hand with cleanliness. The intrusion of dust and debris can wreak havoc on delicate electronics. This article explores the pivotal role of dust collectors, their operation, and their necessity for various PCB depaneling machines. The Dust Collector's Crucial Function Dust collectors, also known as dust extractors, play an indispensable role in PCB manufacturing. When a PCB depaneling machine or a Laser PCB Depaneling machine is in operation, it generates a significant amount of dust. The dust collector promptly engages its vacuum motor to suction fine particles off the PCB, directing them to a collector equipped with a filtration system. Which Models Of PCB Depanelers Require Dust Collector? Several PCB depaneling machines necessitate dust collectors to ensure precision and cleanliness, including: I.C.T-5700 Offline Depaneling Machine, high precision, easy manual operation, dual platform, high efficiency. I.C.T-IR350 In-line depaneling machine, high precision, rapid operation, suitable for integration into the SMT production line for Industry 4.0 and AI automated production. I.C.T-LCO350 Laser cutting ensures cutting accuracy of 0.002, ideal for precise cutting requirements. I.C.T-100A Desktop PCB depaneling machine with compact size and high precision, suitable for smaller-scale operations. The Science Behind PCB Dust Collectors To prevent charged dust particles from adhering to PCBs, PCB depaneling machines are equipped with ionizing guns. These devices emit ions that neutralize static charges, making dust particles less likely to stick to freshly cut PCBs. The Vacuum Effect: Suctioning Away Dust During PCB depaneling, a cloud of dust is produced. The dust collector utilizes a robust suction system, often powered by vacuum motors, to draw dust away from the work area. Collected dust is transported to a designated collection point within the dust collector. A Difference In Design: I.C.T-5700 Vs. I.C.T-IR350 The placement of the dust collection apparatus distinguishes PCB depaneling machines. I.C.T-5700 has a bottom-mounted system capturing falling dust, while I.C.T-IR350 features a top-mounted system preventing dust settling on the work surface. This strategic difference ensures efficient removal of dust and debris, guaranteeing a clean and precise manufacturing process. Check: If you want to learn about the comparison of I.C.T-5700 and I.C.T-IR350. The Importance Of Filter Replacement The efficiency of a dust collector relies on its filter, necessitating periodic replacement every 1-3 years, depending on usage frequency. Regular filter maintenance ensures optimal performance.

If you seek a dust collector for your PCB depaneling machine, contact us today to explore your options. Ensure your operations maintain cleanliness, efficiency, and meet the high standards of modern PCB manufacturing. Don't let dust compromise your precision – let's keep it clean together!...

ACHIEVING EXCELLENT VERTICAL HOLE FILL ON THERMALLY CHALLENGING BOARDS USING SELECTIVE SOLDERING

Nov 14, 2023 | Thomas Shoaf, Joseph Clure, Denis Jean

The continuous drive in the Electronics industry to build new and innovative products has caused competitive design companies to develop assemblies with consolidated PCB designs, decreased physical sizes, and increased performance characteristics. As a result of these new designs, manufacturers of electronics are forced to contend with many challenges. One of the most significant challenges being the processing of thru-hole components on high thermal mass PCBs having the potential to exceed 20 layers in thicknesses and have copper mass contents of over 40oz. High thermal mass PCBs, coupled with the use of mixed technologies, decreased component spacing, and the change from Tin Lead Solder to Lead Free Alloys has lead many manufacturing facilities to purchase advanced soldering equipment to process challenging assemblies with a high degree of repeatability....
