Mechanical CAD Our Engineering Department is comprised of experienced in-house product designers
Though many of our customers come to us with ready-to-make 3-dimensional CAD designs for plastics and sheet metals, we continue to offer design support and consultation if needed. This includes help with early-stage industrial and concept design as well as engineering and mechanical design. At Lampex we utilize the latest in design software including systems for drafting, surfacing and solid modeling. These different packages allow us to handle all aspects of the design in an efficient manner.
Our design engineers, with knowledge of mechanical and electronics, will work closely with you and your team to foster a close working relationship. We can join you at any point in the development of your project and help you move forward. This relationship between the customer and Lampex is what makes Lampex special and gives our customers the best opportunity to succeed. Lampex is the place where your project will get the careful attention to cost and detail that is necessary in order to compete and succeed in today's market.
Many of our customers have found the benefits that our experience in part design can deliver. We are capable of starting from your 2D design, or concept sketch and create a full 3D model offering you a full-fledged part design. Working closely with our customers we can become an extension of your development team. Bringing our unique blend of talents and experience to design a product that is not only functional but also ergonomic and aesthetically pleasing.
We strive to be the best. This means we are constantly updating our techniques and capabilities. Lampex employees take great pride in their work and stand behind every project that has been completed. We believe that you have to succeed and we make sure that it is done right each and every time.
DESIGN TEAM:
A quality product starts with a quality design. Our fully staffed design team is among the most talented in the industry. We are aware of the importance of designing for accuracy, ease of maintenance and reliability. Many of our designers are former toolmakers with a hands-on understanding of the build process.
Getting your product to market on time is a challenge in today's competitive environment. Our engineers are ready to assist you whether it be, product design, concurrent tool design or trouble shooting of new or existing tools. We work with our customers to find the best solutions.
Our dedication to your satisfaction is unprecedented in the tooling industry. Allow us to quote on your next tooling program and you will see why our customers return time and time again. Quality, competitive, on-time tooling solutions that deliver high performance.

FAQ
Q. Which way should I run my tracks on a double-sided board?
A. Usually tracks on the solder-side are run horizontally, and vertically on the component side.
Q. What drill sizes should I use?
A. Usually only a couple of drill sizes are needed. Try to limit the number of drills you use to eight, this avoids extra hassles for the PCB production line people.
Q. How do I get footprints for resistors, capacitors and diodes?
A. In schematic, double click on the component so that you are editing its attributes. Here you can change its designator (e.g. R4), part type (e.g. 100k) and footprint (e.g. axial0.4). These attributes are exported along with the net list, so that PCB knows what footprints to use, and what labels to attach to them.
The footprints you will commonly need are
· 0.25W resistors axial0.4 (Axial explains the way the leads leave the body of the component)
· Small signal or 1A diodes diode0.4 (The 0.4 is 0.4", the spacing of the holes)
· Capacitors rad0.1 or rad0.2 (Rad stands for radial - the way the leads exit the body - radically)
· Electros rb.2/4 (Radial Bipolar, 0.2" lead spacing, 0.4" case diameter)
· ICs dip8, dip14
All the most common footprints are in a library called advpcb.lib. You can add this to the list of searched libraries by using add/remove libraries command.
If you don't import a net list, you can still place footprints of your choosing by simply placing a part. You choose a footprint from the library.
Q. What do you mean by this: Minimum via size 40 thou outer, 25 thou inner.
A. A via is a plated through hole (PTH), placed on the PCB purely to connect two tracks on different layers. For you, this is the top and bottom layers, component side and solders side. Since there is no component leg going through the hole, just the copper plating, we could make the hole any size we wanted. But we keep it above a minimum hole size, so that the drill isn't too tiny, fragile, expensive etc. It also allows them to drill a stack of PCBs at once (say up to about 5 deep). For BEC, this is 25 thou (0.6mm). Then you need a certain thickness of copper pad around the hole, to ensure they can cope with a small misalignment, amongst other things. The ring doesn't have to be big, since we aren't soldering to it. The 40 thou (1mm) is the diameter of the via "pad". This only allows 8 thou (0.2mm) of copper ring, which is pushing the 10/10 rules a bit, when you look at it. I'd be working with 45thou dia. with a 25 thou hole. If you are doing a single sided layout, then you don't even need to know what a via is.
Q. DIL? SIL? DIP?
ADual In Line. Single In Line. Dual In-line Package.
Q. What is a "Thou"? Is a "Thou" the same as a "mil"?
A. A "Thou" is one thousandth of an Inch, 0.001". A "mil" is the same quantity, a milli-inch. I prefer the term thou because it is less likely to be confused with millimeters. Since there are 25.4mm to the inch, 1mm = 39thou. All components originally used imperial measurements, so the thou are a good unit to work with. For example the pins on a normal DIL package are 100thou apart.
If you haven't seen it used before, a single quote ' is an abbreviation for feet, and a double quote " stands for inches. So I could write my height as 5'10".
If you are working in metric, just use millimeters for everything. E.g., I am about 1800mm high. DON'T use cm!
Q. What size grid should I use? How close can my tracks be?
A. Short answer - 12 thou tracks on a 25 thou grid is preferred.
Long answer. Well the old capabilities of most PCB manufacturers were 12 thou tracks with 12 thou clearances (gap between tracks). These are called 12/12 design rules. If you use 12 thou tracks on a 25 thou grid then you have a guaranteed 13thou gap between adjacent tracks. You can run one track between the pads of a DIP and meet the clearance rule if you use 62 thou diameter pads, or at least 62 thou wide anyway. Almost everyone can manufacture to 10/10 rules these days. Some can do 8/8, even 6/6, but you will start to pay for the privilege. However, stick to 12/12 rules unless you have a reason not to. With 10/10 rules you can run two 10thou tracks between 50thou wide DIP pads on a 5thou grid.
Q. What clearances and track widths should I use?
A. On a standard (1 Oz. Cu) PCB, a 0.010" track will carry 0.8A with a 10 degree C rise, plenty for you. But remember to use thicker tracks anyway for power supply traces etc, just in case you short them.
