Happy’s Essential Skills: Computer-Aided Manufacturing, Part 2 - Automation Examples


Reading time ( words)

The Sunnyvale, California PCB facility was built in 1981 and had even more factory automation than Palo Alto, California facility did. The many systems it had were:

  • WIP tracking
  • CNC for drilling
  • Low-volume robot lamination
  • Wastewater treatment process control
  • AOI and Electrical Test
  • Production scheduling
  • Computerized plating and chemical control
  • Laboratory automation of chemical analysis
  • Inkjet individual board serialization for traceability

Figure 14 shows the overall CIM System Information Flow. This was the first implementation of HP’s automation strategy, “The Manufacturers Productivity Network.”

Figure 15 shows four of the automated systems controlled by the CIM network: a) Electroless copper and multilayer desmear line; b) Dual copper-nickel-gold/tin plating lines; c) Automatics chemical analysis, control and dosing; d) Robotic material handling in multilayer lamination.

Optimize Your Etcher for Best Image Quality

11/03/2022 | Christopher Bonsell, Chemcut
When it comes to obtaining high-quality images, many different factors come into play. Typically, most of these factors come down to your imaging equipment and cleanroom; however, there are factors involved in the etching process that can affect the quality of your image. Here are five steps to ensure your etching process is optimized for the best image quality.

Millennium Circuits on The Move

10/31/2022 | Andy Shaughnessy, Design007 Magazine
I recently met with Daniel Thau, CEO of Millennium Circuits Limited, at PCB West. This Pennsylvania-based PCB distributor has been on an expansion path lately, so I asked Daniel to introduce us to MCL and explain where the company is headed. As Daniel says, it’s all about impacting the world in a positive way.

EIPC Technical Snapshot: ‘Tremendous Uncertainty’ in Global PCB Marketplace

10/26/2022 | Pete Starkey, I-Connect007
For the past two years, EIPC’s Technical Snapshot series has kept us extremely well-informed on developments in printed circuit materials and manufacturing technologies. But what is currently happening in the global PCB market, and how is Europe and the rest of the world affected by the current world situation? The 19th chapter (coincidentally on Oct. 19) in the series gave us a privileged opportunity to find out, as two leading industry analysts presented their observations and opinions in a webinar introduced and moderated by EIPC technical director Tarja Rapala-Virtanen.
