Graphene electronic fibres with touch-sensing and light emitting functionalities for smart textiles

Aug 29, 2019 | Elias Torres Alonso, Daniela P. Rodrigues, Mukond Khetani, Dong-Wook Shin, Adolfo De Sanctis, Hugo Joulie, Isabel de Schrijver, Anna Baldycheva, Helena Alves, Ana I. S. Neves, Saverio Russo, Monica F. Craciun

The true integration of electronics into textiles requires the fabrication of devices directly on the fibre itself using high-performance materials that allow seamless incorporation into fabrics. Woven electronics and opto-electronics, attained by intertwined fibres with complementary functions are the emerging and most ambitious technological and scientific frontier. Here we demonstrate graphene-enabled functional devices directly fabricated on textile fibres and attained by weaving graphene electronic fibres in a fabric. Capacitive touch-sensors and light-emitting devices were produced using a roll-to-roll-compatible patterning technique, opening new avenues for woven textile electronics. Finally, the demonstration of fabric-enabled pixels for displays and position sensitive functions is a gateway for novel electronic skin, wearable electronic and smart textile applications....

What are the factors that affect the appearance of IC shipping tubes?

Aug 24, 2019 | James tong

Many customers looking for IC shipping tubes value the appearance of the packing tube. They will feel that if the appearance of the IC tube does not look good, the quality will not be very good, so the first impression of the appearance of the Antistatic ic tube is very important. So what are the factors that affect the appearance of IC tubes?...

Automated Testing with Boundary Scan

Aug 19, 2019 | ACI Technologies, Inc.

Boundary scan is a method for testing interconnects on printed circuit boards (PCBs) or sub-blocks inside an integrated circuit. It has rapidly become the technology of choice for building reliable high technology electronic products with a high degree of testability. Due to the low-cost and integrated circuit (IC) level access capabilities of boundary scan, its use has expanded beyond traditional board test applications into product design and service....

Cracks: The Hidden Defect

Aug 15, 2019 | John Maxwell

Cracks in ceramic chip capacitors can be introduced at any process step during surface mount assembly. Thermal shock has become a "pat" answer for all of these cracks, but about 75 to 80% originate from other sources. These sources include pick and place machine centering jaws, vacuum pick up bit, board depanelization, unwarping boards after soldering, test fixtures, connector insulation, final assembly, as well as defective components. Each source has a unique signature in the type of crack that it develops so that each can be identified as the source of error....

Cleaning Flux Residue under Leadless Components using Objective Evidence to Determine Cleaning Performance

Aug 14, 2019 | Mike Bixenman - KYZEN Corporation, Vladimir Sitko, Pavel Hub - PBT Works

Cleanliness is a product of design, including component density, standoff height and the cleaning equipment’s ability to deliver the cleaning agent to the source of residue. The presence of manufacturing process soil, such as flux residue, incompletely activated flux, incompletely cured solder masks, debris from handling and processing fixtures, and incomplete removal of cleaning fluids can hinder the functional lifetime of the product. Contaminates trapped under a component are more problematic to failure. Advanced test methods are needed to obtain "objective evidence" for removing flux residues under leadless components.</p><p>Cleaning process performance is a function of cleaning capacity and defined cleanliness. Cleaning performance can be influenced by the PCB design, cleaning material, cleaning machine, reflow conditions and a wide range of process parameters.</p><p>This research project is designed to study visual flux residues trapped under the bottom termination of leadless components. This paper will research a non-destructive visual method that can be used to study the cleanability of solder pastes, cleaning material effectiveness for the soil, cleaning machine effectiveness and process parameters needed to render a clean part....

Selective Soldering and the Modular Approach

Aug 08, 2019 | ACI Technologies, Inc.

High mix production is the mainstay of many electronics assembly plants. Lot sizes and board complexities vary and the boards are often mixed technology, comprising a blend of both surface mount and through-hole technology. Modularizing a production line enables a clear distinction between one type of assembly process and another. This article assumes a modern factory where a job can be routed to the selective soldering machine module, the hand assembly bench, or a combination of both. The decision rules of routing a circuit board through hand assembly versus automated selective soldering are discussed. Hand assembly soldering operations require no explanation....
