PALINDROME is Intercept's state-of-the-art backward-engineering product that allows a layout-driven design to back annotate PCB changes and additions to the schematic. A companion product to MOZAIX schematic capture software and PANTHEON PCB / Hybrid / RF design software, PALINDROME compares schematic and PCB databases and, provides valuable design-discrepancy data for RF engineers and PCB designer teams. Using component and netlist information derived from the layout, PALINDROME allows you to automatically and interactively generate new, logically correct schematics.

PALINDROME's backward-engineering features are simultaneously user-intuitive and yet technologically advanced. The product enables designers to choose components to add to the board that are complete with company-specific part numbers and other key properties. Designers may back annotate complete design sections to the schematic that include added Digital, Hybrid, and RF circuitry.

PALINDROME relies on a sophisticated design comparison engine, launched from within Mozaix, to quickly identify component and net differences between the schematic and layout. PALINDROME addresses these netlist differences by automatically updating the instance pins on every placed symbol in order to match the net connections specified in the PCB design. PALINDROME utilizes a company library, or auto-generates parts and symbols on the fly using pin information from Pantheon.

By combining PALINDROME with MOZAIX and PANTHEON, users can now forward a schematic to layout, modify the part circuitry on the board by adding new Digital, Hybrid, or RF sections, import an RF section from another database or third-party tool, and finally back-annotate the schematic to match the PCB released for build. Users can also implement a full reverse engineering flow that starts with importing the PCB from legacy data, perhaps Gerber-only recovery, and finishes with auto-generation of complete schematic and library data.

PALINDROME is now available as an embedded option in the Mozaix version 3.0 release. For additional information about PALINDROME and other Intercept products, contact Intercept by phone at 404.352.0111 or by E-mail at sales@intercept.com.

How We Work
As soon as we receive the information necessary to produce a quotation, the price and delivery date for your PCB design is fixed, unless you make significant changes subsequently. Working closely with you, paying particular attention to any special requirements, we design your PCB. You then have the opportunity to thoroughly check the design ¨C there is a choice of paper check-plots, Gerber files, PDFs etc ¨C whichever you prefer. Any changes/adjustments you require are then made and we submit a final set of check-plots for approval. As soon as you confirm that you are happy with the layout we produce photo-plot and drill files, together with any other files required for manufacturing, assembly and testing of your PCB.When companies are faced with the challenge of manufacturing an undocumented and partially obsolete printed circuit board assembly (PCBA) with only the PCBA as the starting point, the reverse engineering process can be a useful tool for reconstructing the design and production documentation, thus enabling its manufacturability using available and technically compatible components. There are many challenges for the manufacturer in the reverse engineering process, but following some standard process guidelines will increase the probability of manufacturing success and can indefinitely prolong the useful life of an aging PCBA.

Careful planning at the outset is critical to ensure that the necessary equipment, tools, software, expertise, and of course, the PCBAs are readily available. Having several boards on hand provides some flexibility and expediency to the process by allowing some parallel processing of the non-destructive re-engineering steps.

The first step should be the documentation of the components on the board. Access to the various electronic component vendors¡¯ databases (current and previously published catalogues, specifications, cross references, etc.) is a good resource for component types and replacement component part numbers. This identification of components will lead to the development of the bill of materials (BOM) for the PCBA, an important documentation step in reconstructing the production materials needed. Coincident with the BOM development, color digital images of the PCBA should be taken. Detailed images are invaluable in the later reconstruction steps of the board layout.

Various methods and tools can be used to regenerate the electrical design of the circuit assembly. An in-circuit tester can be used to generate point to point connections, which include generating a net list, and determine some or all of the values for the components on the board. A system such as ScanCad can be used to regenerate the Gerber files for each layer of the board. X-ray imaging can also help clarify point to point connections. These tools are essential for efficient reverse engineering.

Conformal coating of the PCBA can complicate the task. The type of coating and how to remove it without damaging the board assembly will determine the overall level of difficulty for the reverse engineering process. If the type of conformal coating is not known, observation and testing will help identify the type of coating and the process required for removal. Several removal techniques are available, including using solvents, peeling, thermal, grinding and scraping, and micro-blasting. After removing any conformal coating, component removal can begin. Great care must be taken to insure that the underlying board remains sufficiently intact. Proper use of the right tools and equipment will save the board from damage and preserve it for any remaining analysis.

Up to this point, a list of components on the PCBA should be available from the BOM. Information gathered from an in-circuit tester and/or x-ray machine will be used to develop the design schematic. With this data and the BOM, one can use any of a number of computer aided design (CAD) software packages capable of circuit design and layout to generate the Gerber file, which is the machine code for circuit artwork. This may not replicate the same layout as the original PCBA and depending on the end application, further design work on the PCBA may be necessary to create the replacement design.Mechanical Design:

Reverse Engineering - Conversion from paper to CAD

Many printed circuit board (PCB) fabricators and vendors claim that there is no easy way to take a PCB apart, layer by layer. Most boards are made of prepreg with an epoxy resin, a copper-clad surface etched for the circuitry design, patterned solder mask, a silkscreen print of the reference designators, and a finish plating on the exposed copper. These materials are designed to keep the PCB intact and to prevent separation, and to conform to strict commercial standards (designed to ensure PCB quality and reliability) but do make the task of separating the layers very difficult.

The board must be separated, layer by layer, which requires effort and patience. In some cases, a poorly constructed board can be separated mechanically using a knife and then pried apart (Figure 3-1).

A chemical application may be needed to help separate the layers without damaging the board. Methyl Ethyl Keytone (MEK) can soften the epoxy that bonds the layers together. This technique was developed through small sample testing on a modern, well-laminated board. The key process variable was to determine the quickest method to get the MEK soaked into the PCB. One sample was soaked in MEK for a set time period, another was soaked in MEK and then heated to 40¡ãC, and the last was dipped in MEK for a few seconds. In this trial run, it was determined that heating of the MEK helped the PCB absorb it more rapidly. Caution should be taken when working with MEK. Please consult the MSDS. When the PCB is fully soaked, there is not much time before the MEK evaporates and the board re-hardens. This process of delaminating will take longer to work through a thicker board. Figure 3-2 shows the result of this technique.Do you need a PCB design service bureau?
Does your work bench resemble the picture below?

You are highly creative. You produce valuable products. You're an electronics design engineer.

You deserve a competent printed circuit board design shop.

One as trustworthy as a Tektronix oscilloscope.
Now that's probably a new thought for you. When you are thinking of a PCB designer and a reliable scope, you might be remembering that that scope came in handy while you were debugging some designer's botched-up artwork. You provided a schematic and netlist, he laid out the board, the board was built and it didn't match the schematic. So you had to reverse-engineer your own circuit to find out what the printed circuit designer did.

We would like to indicate that that was an untrustworthy PCB designer.

Now let's roll back the clock. Imagine that you had used a shop whose designers had followed a standard policy which eliminates at least 90% of artwork mistakes by its simple application alone. And as for the other 10%, suppose also that those designers had been trained in and had used good design practices which practically close the door on any possibility of botched-up artwork. Well that would be a reliable PCB design service bureau, wouldn't it? And you could put your trusty oscilloscope to better uses.

Such are the designers of Golden Gate Graphics. Give us a look. We'll do our best for you.
