Current IssueCounterfeit Concerns
The distribution of counterfeit parts has become much more sophisticated in the past decade, and there's no reason to believe that trend is going to be stopping any time soon. What might crop up in the near future?
Solder Printing
In this issue, we turn a discerning eye to solder paste printing. As apertures shrink, and the requirement for multiple thicknesses of paste on the same board becomes more commonplace, consistently and accurately applying paste becomes ever more challenging.
A Culture of Thriving
One cannot simply command thriving; it must be nurtured, developed, and encouraged. In this issue, we explore strategies to improve your working relationship model—both internally and externally. In this culture of thriving, your business will grow in the process.

PVA to Highlight Conformal Coating Solutions at NEPCON South China
July 23, 2018 | PVAEstimated reading time: 2 minutes
PVA announces plans to exhibit at NEPCON South China, scheduled to take place Aug. 28-30, 2018 at the Shenzhen Convention & Exhibition Center. Company representatives will highlight a Delta 8 Selective Coating/Dispensing System with a VPX-2KS Dual Component Spray Valve, as well as its Delta 6 Selective Coating / Dispensing System with a FCS300-ES Stainless Steel Extended Spray Valve and a JDX Jet Dispense Valve.
The Delta 8 maintains the preferred features of previous workcells, and features a robust overhead three-axis motion platform suitable for inline or batch operations. Improved structural and gantry rigidity have been added for robustness and easier access. Delta 8 has a maximum acceleration of 0.5 g, and a footprint 1046 x 1270 x 2350.9 mm (41.18" x 50.0" x 92.56").
The Delta 6 shares the same features as the Delta 8, but has been designed with a slimmer footprint of 847 x 1136.9 x 1606 mm (33.35" x 44.76" x 63.23"), and a maximum acceleration of 1 g.
The VPX-2KS Dual Component Spray Valve being shown with the Delta 8 is a progressive cavity metering valve capable of accurately spraying 2K chemistries in a clean, flexible atomized process. The VPX-2KS has many integrated features including:
- High-precision ±2% (material dependent)
- Servo controlled
- Programmable 1:1-10:1 ratio
- Works with filled or unfilled fluids
- Will not damage or alter filler properties syringe, cartridge or remote reservoir feed
- Easy disassembly and cleaning
- Ability to process short pot life mixtures Integrated pressure monitoring at the pump outlet
The FCS300-ES Extended Spray Valve that will be featured with the Delta 6 provides a repeatable, concentrated coating film in circular pattern widths ranging from 0.125"-0.5".
The FCS300-ES has many integrated features including:
- Low pressure, low volume atomized process
- 300 series stainless steel fluid body for superior material compatibility
- Micrometer flow adjustment with lock nut
- Divorced valve design prevents material contamination of the air section
- Compatible with all commercially available conformal coatings
- Wide viscosity range offers versatility for virtually any spray application
The JDX Jet Dispense Valve, also being shown with the Delta 6, is an extremely fast, non-contact jet dispenser that precisely dispenses viscosities up to 400,000 cps, while its unique diaphragm design saves time and money. The valve offers unparalleled repeatability, and with no z-axis movement to slow it down, can move swiftly and easily to jet into even awkward, hard to reach areas. Its unique diaphragm design allows fast cycle rates due to its very small mass. This distinctive design features a single, easily replaceable diaphragm that eliminates the dynamic fluid seals, common in other jets, and the need to remove the jet from the robot, clean and replace worn seals.
About PVA
PVA was founded in 1992 by president Anthony Hynes, when he began selling dispensing valves for automated and manual dispensing applications out of his home. From modest beginnings in Upstate New York, to a 105,000 sq ft facility in Cohoes, NY, with regional sites stationed throughout North America, Europe, and Asia, PVA has a long history of providing innovation and expertise in dispensing, coating and custom automation.
For 20 years, PVA has been making manufacturing easier with customer driven solutions used in industries ranging from solar, semiconductor packaging, printed circuit board assembly, medical device manufacturing, and consumer electronics. From benchtop equipment, to inline conveyor systems, we evaluate each opportunity independently, and without limitation, to ensure you make the most reliable product possible.
Headquartered in Upstate New York, with regional sites stationed throughout North America, Europe, and Asia, all PVA Systems are backed by a 24-hour global service network, including regionally trained technicians for fast response times.
