Introducing the New FlexCell, Flexible Gantry Robot Workcell
Selective Conformal Coating, Fluid Dispensing, Jet Dispensing, Plasma Treatment, Meter-Mix Dispensing, Potting, Encapsulation & Inspection

ETS Energy Technology Systems will begin rolling out a new generation of Flexible Robotic Gantry Workcells called FlexCell this coming October 2017. The FlexCell plastform comes equipped with a multi-axis gantry robot based on Ultra Precise, Linear Motor Technology. FlexCell can be equipped with multiple end effectors including Selective Conformal Coating Valves, Fluid Dispensing and Jetting Valves, Plasma Treatment Nozzles, Meter-Mix Dispensing, Potting, Encapsulation, CCD Vision and Inspection devices. The new FlexCell platform comes equipped with many new standard features to improve user operation and provide exceptionally long factory life. A few of the new features include:

  • Robust frame design to cater for longevity and lasting machine accuracy
  • A lighter coating head design that enhances dispensing flexibility and durability
  • Optional pallet return conveyor under the FlexCell machine to fully automate the automation line with our curing ovens and board handling equipment
Atmospheric Plasma Treatment

What is Plasma?
Plasmas are the fourth state of matter and believed to be the most common state of matter in the universe. In simple terms, plasma is an ionized gas into which enough energy is provided to free electrons from atoms or molecules and coexist in both the negative and positive state (Kross, Brian. “What Is Plasma?” Jlab.org. Jefferson Lab, n.d. Web.).

Solid + Enough Energy = Liquid
Liquid + Enough Energy = Gas
Gas + Enough Energy = Plasma

Preventing Delamination of Conformal Coating on Printed Circuit Boards

Preventing Delamination of Conformal Coating on Printed Circuit Boards

by Eric Sari

When it comes to delamination on printed circuit boards (PCBs), don’t immediately start making adjustments in your process or selective conformal coating machines while checking for the cause of defects. First, check to see if the problem is a condition present on the batch of boards itself. Conformal coating delamination is generally caused by a condition present on the circuit assemblies and the issue is much easier to fix than your conformal coating equipment or the process itself. Poor adhesion of conformal coating on PCBs is frequently the result of poor environmental conditions in which the boards endured before arriving to the conformal coating workcell. The following are a few common issues to check for when troubleshooting the root cause of delamination of conformal coating on PCBs.

Temperature and Humidity on Selective Conformal Coating
It is well known that selective conformal coating on printed circuit board (PCB) assemblies provides unparallel protection for PCB’s. Nevertheless, concentrated conditions of humidity, water, and high temperatures can have negative effects on the conformal coating itself causing it to fail and become inapt for its intended purpose. Taking this into consideration, it is prudent to choose the right type of conformal coating that best suits the application and environmental conditions under which an assembly is likely to undergo in use. The proper conformal coating will significantly reduce the likelihood of failure/rejection, saving both valuable time and money for any manufacturing process.

Ultraviolet (UV) Curing Technology

Ultraviolet (UV) Curing Technology

by Wes Noble

What is UV Curing?

“Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 400 nm to 100 nm, shorter than that of visible light but longer than X-rays.” (Source: Wikipedia). Ultraviolet or UV curing is used to create a photochemical reaction using high intensity Ultraviolet (UV) energy or “light” to quickly dry inks, adhesives or conformal coatings. Most materials cure with a UV wavelength around 350 ~ 400nm although some materials require UVC energy near 255nm. There are many advantages to using UV curing over other traditional methods of curing. Not only will it increase production speed, it assists in creating a better bond, and improves scratch and solvent resistance. When compared to other methods of curing, UV curing generates a more reliable cured product at a much higher rate of production in a considerably shorter period of time.
