The MYSmart series and Mycronic’s jet printing technologies make it possible to solve any dispensing or conformal coating challenge. Now Mycronic is establishing multiple application centers worldwide to help customers make the most of them.

New application centers worldwide

With a larger global installed base of MYSmart and MY700 jet printing and dispensing systems, Mycronic is taking the next step in bringing its hands-on expertise closer to customers by establishing multiple new application centers for dispensing and coating in the US, Europe and Asia.

The centers offer customers a complete service offering, from prototyping and process development to automation and software integration.

Creating tomorrow’s opportunities

Mycronic’s new application centers are designed to function as a practical interface between Mycronic and its customers, across industry sectors and among industry partners.

“At a typical technical seminar for coating,” says Koppens, “we bring together several leading manufacturers of coating and dispensing fluids and inspection systems to explore future demands in electronics protection. To find new ways to help our customers get more from our systems, we really need to collaborate and stay at the forefront of new applications.”

“Show us your application. We’ll help solve it.”

To date, the new centers have handled dozens of customer projects, with many more in the pipeline for 2019. From advanced process control and traceability systems for automotive electronics manufacturers to new adhesive fluid trials for consumer electronics.

"We really have the chance to better understand our customers’ production environments and set up the right process to get them off to the best possible start. So if you’re looking into ways to improve your process, show us your application. We’ll help you solve it,” Koppens explains. 

Several process improvements benefiting the customer

A number of process improvements have already resulted from several customer collaborations. “One example is a pre-heat buffer conveyor,” explains Koppens, “which we developed for a customer primarily to reduce energy consumption in the dispenser. By pre-heating the board up to ninety degrees, it also ensures a more stable process with a shorter cycle time.”

Another service offering that has experienced strong customer demand is application development, where specialists from Mycronic help to optimize a particular board design for the dispense application, to reduce cycle times or to minimize production costs.

Rising demand for dispensing and coating

Mechanical integrity is increasingly crucial for today’s electronics. Whether it’s electric toothbrushes, car electronics or wearable devices, more and more devices are exposed to moisture, impact, thermal stress and other harsh environments. Dispensing and coating systems are therefore essential to ensuring longer lasting, high-quality products.

The need for precise and selective protective coating is quickly expanding into a wide range of board designs and manufacturing environments. “In Europe and the US, conformal coating is growing more important for all kinds of automotive, aerospace and medical electronics,” explains Koppens. “In Asia we see a lot more focus on smartphones, cameras and other consumer electronics – typical high-volume applications.”

When it comes to dispensing, some of the growing challenges are driven by a wider mix of components, higher component density, and a general demand for more robust finished products.

“Underfill, for example, is crucial for BGAs, since an epoxy underfill gives better strength, resistance to thermal stress, and protects against moisture and other contaminants,” says Koppens. “And powerboards, which tend to have a lot of large and tall components, usually need high-viscosity silicones to improve mechanical strength.”

All of these applications require high-precision dispensing systems that can accommodate a variety of fluids while being flexible enough to integrate into existing production systems.

Solving solder defects

Solder paste deposits represent yet another rising quality challenge for electronics manufacturers. With Vi TECHNOLOGY inspection systems as part of the Mycronic family, it has now been verified that 70–75 % of failures in electronics production are due to the stencil print process used by most facilities. These stencil processes are particularly limited when it comes to handling large variations in solder paste deposits.

With the dual-head MY700 Jet Printer and Jet Dispenser, the advantages of jet printing can be leveraged in production environments of any scale.

  • Smaller high-mix manufacturers can achieve perfect quality solder deposits at high speeds, apply high-precision adhesive fluid deposits, or a combination of the two.
  • Mid-volume producers can ramp up speeds by combining two MY700s, using a dual large-dot ejector for higher throughput together with a dual small-dot ejector for more challenging precision deposits.
  • High-volume stencil printer lines can benefit from the MY700 as part of an add-on program, which makes it possible to solve quality issues in challenging processes while simplifying stencil designs.

The MYSmart series goes global

The introduction of the MYSmart dispensing series also marked a significant expansion of Mycronic customers’ capabilities into any type of electronics assembly processes, offering a complete portfolio of tabletop and inline dispense solutions, together with a versatile conformal coating system.

First launched in 2017, the series incorporates a portfolio of core technologies used by leading global automotive, aerospace and consumer electronics, upgraded with high-end standardized features for the global market. Standard features across the range include precision robotics, high-accuracy laser detection systems, automated calibration routines, high-speed jetting and more.
