Custom Applications : Custom Lead Forming Applications

Below are two examples of custom applications that illustrate Fancort capabilities.

We have many more in our 47-year history of designing and building surface-mount lead forming equipment.

PROGRESSIVE SYSTEMS FOR PACKAGES ON LEAD FRAMES

Progressive Systems for Packages on Lead Frames

Fancort will design and build progressive tools to process any type of plastic, metal or ceramic package that is produced on a lead frame. The tools are compatible with manual or semi-automatic feeding depending on your budget and production requirements. Progressive trim and form tools, depending on the design, normally consist of from three to five punch and die stations that might incorporate the following operations:

  • Dejunk of plastic between leads
  • Removal of dam bars between leads
  • Cutting of tie bars to set lead length
  • Final forming to footprint specifications
  • Singulation of finished device

 

Tooling holes in the lead frame are used for location by the operator to hand feed from one position to the next. Estimated throughput is 200-400 parts per hour depending on the number of stations used to produce a finished part. A less expensive approach to full progressive tooling:

Combine the features of a progressive tool with a stand-alone form and trim tool to keep cost down.

The tooling would dejunk, remove dam bars and singulate the device. The device would then go into a stand-alone tool for final form and trim.

An alternate would be to use a Fancort universal trim and form tool as the stand-alone and have the flexibility to vary the final footprint.

5000L-8 (2 ton) or 5000L-10 (5 ton) is the standard air pressure, we recommend for most progressive tooling applications.

DIPs TO SMDs

  • Standard Gull-wing design or optional configurations
  • Two-stage processing eliminates stress
  • Consistent standoff control and coplanarity
  • Process plastic or ceramic packages
  • Manual feeding
  • Fits Fancort Model 5000 air press
  • Optional tube holder for finished parts
  • Optional track to hold unformed parts
  • Space grade rad hard parts with an Inverted Gull-wing J type SMT form

P/N D-4 Fixed built-in standoff height
P/N D-4A Adjustable micrometer standoff control. Adjustability is limited by package construction and the standoff tabs on the leads but generally can be .015-.050 “A” on our drawings

TAB EXCISE AND FORM

  • Excise and form or excise only

  • Ball-bearing die set

  • Chrome plating

  • Optional loader/unloader

  • Fits model 5000L air presses

TO CAN FORMING

  • TOF-3 form tool with built-in hand press forms to larger bolt circle, square or DIP configuration
     
  • Leads can be formed with minimum standoff of .040"
     
  • Mechanical lifter to remove formed parts
     
  • Comes with prep tool to straighten leads before forming
     
  • Cutting of leads before forming can be done on our D-2C machine
     
  • TOF-4 with hand press will form and cut radial cans for surface mounting
     
  • Plated to prevent rusting

OPTICAL COMPONENT FORMING

Lead Trim and Form Equipment For Optical Components

Fancort will design and build trim/form tools for surface-mount or through-hole applications for a wide variety of optical components. We can help you with the design parameters that allow the part to be properly formed with sufficient lead length. These tools are designed to prevent stress to any of the delicate areas, including any glass seals.
