Conformal Coating Thickness Measurement

Oct 13, 2013 | Dr Lee Hitchens

The measurement of the conformal coating thickness on a printed circuit board (PCB) to ensure internal and international standards are met is now a critical factor in conformal coating process control. There are several methods for measurement of conformal coating thickness and they fall into two categories. These categories are wet film measurements applied during coating application and dry film measurements made after the coating is dried enough not to damage the coating....

Designing Circuit Boards for Selective Robotic Coating Application

Oct 13, 2013 | Dr Lee Hitchens

Designing circuit boards for selective robotic spraying of conformal coating can be straightforward if you follow some design rules. Follow them and you can save money and time in your application process. However, if the rules are not followed, the resultant circuit board design can challenge even the most sophisticated conformal coating system and its operator to achieve the finish desired. ...

Choosing the Right Valve for a Selective Robotic Conformal Coating Application Process

Oct 13, 2013 | Dr Lee Hitchens

When investigating the option of a selective conformal coating process it is crucial to consider the right robotic system and valve combination for the material and circuit board that you wish to coat. To fail to do this can lead to difficult process problems in the production line. This article reviews the various valves available and how they can be used with the typical conformal coating materials in the market and highlights some of the key considerations....

The Importance of Viscosity in Conformal Coating Process Control

Oct 13, 2013 | Dr Lee Hitchens

There are numerous factors which directly affect the conformal coating process to greater or lesser degrees. Those which have major impacts irrespective of the substrate / PCB and assemblies include choice of coating material and method of application. Whether conformal coating boards by dip, robot, batch spray or brush methods the viscosity of the coating is a critical factor in the overall process control....

Printed Circuit Board Technology Inspired Stretchable Circuits

Oct 10, 2013 | J. Vanfl eteren , M. Gonzalez , F. Bossuyt , Y.-Y. Hsu , T. Vervust , I. De Wolf , and M. Jablonski

In the past 15 years, stretchable electronic circuits have emerged as a new technology in the domain of assembly, interconnections, and sensor circuit technologies. In the meantime, a wide variety of processes using many different materials have been explored in this new field. In the current contribution, we present an approach inspired by conventional rigid and flexible printed circuit board (PCB) technology....

Pyrolysis of Printed Circuit Boards

Oct 03, 2013 | T. R. Mankhand, K. K. Singh, Sumit Kumar Gupta, Somnath Das

Printed Circuit Board (PCB) is an essential component of almost all electrical and electronic equipments. The rapid growth of the use of such equipments has contributed enormously to the generation of large quantity of waste PCBs. The WPCBs not only contain valuable metals but also a large variety of hazardous materials. Conventional treatments of such WPCBs have their own limitations. By pyrolysis of WPCBs, it is not only possible to obtain the organic part of it as a fuel or useful chemical but can make further processing to recover metals much easier and efficient. In the present work, a kinetic study on the low temperature pyrolysis of WPCBs using a thermogravimetric analyser has been attempted......

Conformal Coating Process Characterization Considerations

Sep 25, 2013 | Brad Perkins, Nordson ASYMTEK

Conformal coating is an enabling process that allows for the ruggedizing of electronic devices and modules. As the process increases the durability of electronics that are subjected to various end-use environmental conditions, it adds value to the product. While it does add value, consumers and manufacturers expect the electronics to work when subjected to dirt, humidity, moisture, corrosive materials, and various other contaminants. This expectation results in a drive to minimize the cost of the process. The lowest cost of ownership for a conformal coating process occurs by utilizing automated selective conformal coating equipment....

Reliability Performance of Very Thin Printed Circuit Boards with regard to Different any Layer Manufacturing Technologies.

Sep 19, 2013 | Gerhard Schmid, Martin Fischeneder, Gerhard Stoiber

The next generation of smart phones will demand very thin multi-layer boards to reduce the product thickness again. This paper shows three different manufacturing approaches, which can be used for very thin any-layer build-ups. The technological approaches are compared on reliability level – the any-layer copper filled micro-via technology which is to be considered as state of the art technology for high end phones and the ALIVH-C/G technology that is well established in Japan. A test vehicle design featuring test coupons for comprehensive reliability test series has been defined as target application for investigation......

Improving Product Reliability through HALT and HASS Testing

Sep 09, 2013 | Mark R. Chrusciel, Cincinnati Sub Zero

HALT & HASS technology uses a combination of accelerated stresses to expose product flaws early in the design and manufacturing stages, which improves product reliability and customer confidence. HALT & HASS is used to uncover many of the weak links inherent to the design and fabrication process of a new product as well as during the production phase to find manufacturing defects that could cause product failures in the field....
