HEPCO Die Sets
How to Place Custom Orders
Ordering Custom Die Sets for your
HEPCO equipment is now easier than ever!
The simplest way to order HEPCO die sets is
to mail, fax, email or phone in an order using our "Basic Die Sets"
information from our catalog. HEPCO accepts VISA, MasterCard,
cashier's checks, money orders, company checks, and purchase orders by
fax. In addition to a detailed print with dimensions, it is ALWAYS a
good idea to send in samples of the exact components you'll be
running, (and sample PCB when possible) so that there can be no misinterpretation
or confusion when it comes time to build the die set.
RFQ or Order Packages mailed to HEPCO should include
1. COMPONENTS & PCB:
- Bulk - At least 10 sample parts that are the
EXACT ones you will be running.
- Taped - At least 100 sample parts that are the
EXACT ones you will be running.
- Tube - At least 1/2 of a tube of the EXACT
parts you will be running. (Collection tube also, if desired)
- Connectors for trimming - At least 5 of the
EXACT components you will be running.
- At least one PCB with desired holes clearly
Even if they are hand drawn, good prints are essential for our engineers to
fully understand each particular application. In almost all cases, HEPCO
machines reference from the bottom of the component. This means that all the
forms and cuts will be measured from the bottom of the component, and NOT the
heat sink hole. The only time it’s valuable to take measurements from the
heat sink hole on TO-220-style components is when the part will be secured
using this hole. (HEPCO does make dies for the Model 6500-1, 6200-1, and the
3000-2 that are referenced from the heat sink hole, if required.) Otherwise,
variations in components from supplier to supplier, and even BATCH TO BATCH
can result in inconsistent results. Often times, the tolerances called out by
our customers are far narrower than those specified by the device
manufacturer! It is critical to weigh these factors when ordering a die to
make sure satisfactory results are achieved.
To some people, the information we require to build a die seems overkill or
unimportant, but it is the most important factor in ensuring that what you
need is what you get. The small effort spent in order to gather this
information is well worth it, because it allows you to think the
application through before placing the order. Your familiarity of the
particular need will also pay dividends when talking with us about it over
the phone. As a precaution, we prefer to work with samples. This helps
eliminates any guesswork. As shown in our “Basic Die Set” catalog pages, each configuration could
require several different parameters and dimensions in order to get it right.
The most important basic dimensions are:
a. Overall lead length.(unformed component)
b. Lead Diameter.
c. Lead Spacing. (before AND after forming)
d. “Body-to-bend”. (distance between the bottom of the component and the
e. “Body-to-PCB”. (distance between the bottom of the component and the PCB)
f. Board thickness.
g. Lead protrusion. (length of lead sticking out below the PCB)
h. PCB hole diameter.
i. Lock-in? (Y/N)
j. Any other important info regarding your parts, PCB, or application.
(angles, radii. etc.)
Please don’t forget to include your business card and a note explaining what
it is you need! This is also important for Request for Quotes (RFQs). Tell us
how/when to reach you, and what model number you're interested in. Provide
shipping instructions including carrier, account number, service, and
shipping & billing addresses.
If you don't find what you need in our
catalog, DON'T PANIC! We can make custom dies to form or cut thousands
of different components and combinations. Just call and ask if you are not
sure. Just make sure you follow our general guideline on the information
required for HEPCO to make a custom die:
1. Download these .pdf files showing our
most popular diesets, and identify which style of die you need. (Adobe
Acrobat Reader required)
2. Create a drawing (use a pencil and
napkin if necessary) that includes the following dimensions and information:
a. Machine model number and serial number.
(3000-2, 6500-1, 1800-1, etc.)
b. Type of component. (axial resistor, radial
capacitor, TO-220, TO-18, DIP IC, etc.)
c. Number of leads.
d. Desired die type from Step 1 above. (or
e. Written description of desired form/cut
f. Special considerations or instructions.
g. Parts packaging. (Bulk, Tube, Tape, etc.)
3. Fax or email the above info, along with
your contact info and a short description of the application.
If you already have digital drawings of your
particular application(s), you can email
them to our Engineers. Please remember
to include ALL of the information listed above so that our friendly and
knowledgeable staff may reach you to discuss your needs in person. Our Customer Service and Sales department
is always available live via phone between 8:00am and 5:00pm Pacific time to
answer any questions you may have.
