December 2009 Paula Etsy and Jamie White Abstract: Do you have customers located in the European Union (EU)? Does your customer or customer’s customer sell products to organizations in the EU? If either of these answers is yes, then the products that are being produced by photochemical machining processes within the manufacturing supply chain could [...]

March 2009 Paolo Iellici, Chemical Machining Spa Abstract: Since joining PCMI in 1994, regeneration has been a recurrent topic. Everybody talks about it, almost all companies worldwide use it, and everybody thinks about it in a different way. It is quite simple to understand the interest in the topic, as it could allow us to [...]

March 2009 Richard Beaupre and Joseph Beck, ChemArt Company Members of the PCMI all know the PCM process has adapted itself to many industries, from PCB to electronics to aerospace. The difficulties in securing new business in today’s marketplace ranges from overseas competition and downturns in the economy to the lack of basic understanding of [...]

December 2008 From Chemical Milling to Precision Metal Forming: Part B – Additive Technologies Complete the Process Chain Gerald Muelle-Ensslin, HMS Hollmuller As structures become finer, less than 1 mil, the thickness is often in the 5µm area and less. This is the range where it is advantageous to use additive technologies to achieve tight [...]

December 2008 Harrie Knol, Strok Veco In the past, several speakers at the PCMI Conferences have talked about the fact that photochemical milling (PCM) is still rather unknown in the world of mechanical and design engineers. However, photo electroforming (PEF) is even more unknown. This article discusses the photo electroforming process, highlighting the accuracy of [...]

September 2008 Gerold Mueller-Ensslin, HMS Hollmuller Abstract: Trends indicate that thinner, finer, more complexity and higher integration are becoming the norm. Classical chemical milling is a subtracttive process which typically has structures down to 50µm (2 Mil). Precision metal forming is typically a combination of addictive and subtractive processes with structures often under 50µm (2 [...]

June 2008 David Allen, Wei Wang, and Heather Almond Abstract: This paper summarizes the presentation given to delegates attending the PCMI Technical Conference in Hong Kong in March 2008. Currently, there is a great demand for microfabrication, especially in the fields of aerospace, microelectronics, biomedicine, automobiles, and communications.

June 2008 Don Ball, Process Engineer, Chemcut Corporation Juming Wang, Asian Business Manager, Chemcut Corporation Abstract: In August 2006, a customer requested a test to etch 50µm lines and spaces in 18µm foil that had been panel plated to a total thickness of 30µm.  Because the final etch results are so dependent on pre-process steps [...]

March 2008 Jack Rink, R. Michael Donovan & Co. The following article is highly recommended, not only for manufacturing company managers but for all company employees. A decade ago the debate about manufacturing leaving the U.S. focused on the “giant sucking sound” of jobs being pulled into Mexico. Today, the sound is louder and more [...]
