EMI/EMC/ESD Polyonics Antistatic Tapes Solve ESD Problems Before They Damage Static Sensitive Devices Polyonics antistatic tapes and films have proven effective in helping prevent ESD events in static sensitive devices (SSD). The tapes offer surface resistances at the heart of the static dissipative range, 10^5 to 10^9 ohms, that help safely dissipate triboelectric charges before they can cause ESD events. In addition, the tapes also produce very low peel voltages (<100 v) when their liners are removed further protecting components from static charges. The engineered tapes and films are ultra-thin for tight tolerance components. Their durable, static dissipative topcoats allow the tapes to even protect wear surfaces from triboelectric charges. Polyonics antistatic tapes are offered in a variety of materials and constructions and in both single and double coated configurations. Single coated versions are offered for protection, insulation and isolation of SSDs. The double coated versions are suitable for bonding and attaching static sensitive components. The antistatic tapes are available in a variety of configurations with acrylic or silicone PSAs and liner selections to help optimize each die cut operation. In addition, tapes are available with both antistatic and halogen free UL94 VTM0 flame retardant (FR) protection. Custom constructions are also readily available. Select-A-Shield RF/EMI Shielding Products No RF/EMI isolation challenge is too small or too large for Select Fabricators, Inc. All Select-A-Shield RF/EMI shielding products are flexible and highly conductive. Select offers standard and custom sizes as small as an automobile key fob and as large as room-size enclosures. Select-A-Shield enclosures, curtains and pouches make it easier to develop, test, produce and isolate electronic devices. Select offers a full line of over 40 standard models of Select-AShield RF / EMI enclosures including pouches, curtains, tabletop and freestanding enclosures, mobile forensic pouches and forensic enclosures. Options include lighting, air-conditioning, cable sleeves and a choice of filters/connectors. Select-a-Shield RF / EMI products are constructed with RoHS compliant, durable, lightweight, Silver/Copper/Nickel and Nova Select fabric, Selects’s proprietary conductive material. This flexible material delivers maximum attenuation averaging -85 dB in shielding effectiveness in the range of 30 MHz to 1GHz and an average of -80 dB of shielding effectiveness in the range of 1 GHz to 10 GHz. “We developed this US based fabric to yield high conductivity for the widest range of applications,” said Lynne Woodworth, chief development officer, Select. “We’ve done everything from die-cut parts to a shielded enclosure large enough to hold a tractor. The possibility to design shielding that assures RF / EMI isolation from off-the shelf standard configurations to custom designs is what drives SELECT.” 20 Lista International Releases ESD Workstations Lista International Corp. offers its electrostatic dissipative (ESD) Workstation Systems certified to meet specific electrical property requirements assuring static dissipation at a safe rate. Lista pedestals and workbench components can be protected by static dissipative powder-coat finishes that are available in three standard colors. The workbenches also feature work surfaces and shelves with static dissipative plastic laminate. Work surfaces and shelves have ground bolts with a 12 foot grounding cord assuring contact for proper grounding. Lista Workstation Systems can be configured in a variety of heights and lengths, with cabinet pedestals and/or legs. By offering flexibility of components, Lista enables users to create a workbench suited to specific needs without custom cost. To further customize the workstations, Lista offers a variety of accessories, from electrical outlets to riser shelves to parts racks. Lista ESD drawer storage cabinets can serve as pedestals for the workstations. In addition, a broad selection of dividing and partitioning accessories as well as conductive plastic boxes for the cabinet drawers allow users to create customized storage compartments. This feature provides the flexibility to accommodate changing storage requirements. Pulse Electronics Introduces Pin-in-Paste RF MoCA Filter Modules Pulse Electronics Corp. has introduced RF MoCA (Multimedia over Cable Alliance) filter modules that are pin-in-paste compatible. Pin-in-paste manufacturing uses a reflow instead of a wave soldering process to apply solder to the components, saving time, increasing throughput and reducing costs. These filters are compliant with MoCA 1.1 and 2.0 requirements and are qualified with leading MoCA silicon vendors. A filter module can be configured as a multiband diplexer /triplexer with CATV, satellite and DOCSIS (Data Over Cable Service Interface Specification) frequencies with an optional built-in surge protection. They can withstand a maximum reflow temperature of 260°C and operate over an extended temperature range of -40°C to 85°C. The pin-in-paste method (also called pin-in-hole, intrusive reflow or through-hole reflow technology) is a process that allows through-hole components to be reflow soldered instead of wave or hand soldered. Using solder reflow eliminates the cost of wave soldering equipment, saves manufacturing floor space, is a no-clean soldering process, reduces heat stress at the component level, is compatible with existing processes, and results in higher reliability at the printed circuit board level due to fewer soldering processes. With pin-in-paste technology, the RF filters can also be inserted into the PCB using industry standard pick-and-place equipment, eliminating the need for manual component placement. Pulse’s RF filters are designed to provide maximum isolation between the bands with high levels of return and insertion loss. Pulse offers catalog and MoCA IC suppliers qualified filters to meet the specific needs of each customer.
