High accuracy without changeovers

Fancort's dedicated tooling is designed for high quality forms with the most accurate tolerance. With low to high production and less handling than our universal systems these tools are ideal for typical military parts that are expensive and need to be formed correctly 100% of the time.They process all sides of a two-sided flat pack or quad pack at one time. The body of the part floats free when the leads are clamped to insure that no stress is transferred to the body of the device being formed. They are available with manual standoff control or our patented electronic floating anvil system to automatically control standoff height. Semi-automated systems for hands-off processing are also available. These tools can also process typical Aerospace parts for SMT Omega bends and "C" or inverted gull wings.

Dedicated Tooling: Floating Anvil System

Paring a floating anvil press with a dedicated die allows for automatic standoff height measurement and eliminates changeovers. Complete system shown here consisting of the floating anvil press and floating anvil dedicated die. Automatic Standoff Control patent #4,907,628.

A micrometer controls standoff, the system requires 110/1/60 Voltage standard, 220 Voltage optional and 80-100 psi of air pressure.

Dedicated Tooling: Manual Standoff Control Tooling

These are our most common high quality dedicated tools, for flat packs and quad packs needing precision standoff control. These tools can operate in almost any press, hand or air. They have a manual adjustable and lockable micrometer that allows you to control and set the standoff height, if the body thickness varies. The micrometer is available in inch or metric and is, also, now available with electronic / digital readouts for our international and domestic customers. These tools can process 1, 2 or 4-sided parts for SMT and standard gull-wing and can, also, be specially configured to produce Omega bends, for when maximum strain relief is required.

Features

• Accurate registration via outside lead frame on quad-packs for easy part removal
• Connection for ESD protection
• The body of the part floats free when the leads are clamped to insure no stress is transferred to the body of the device being formed
• Coplanarity of .004" or better
• Lifter mechanism on quad-packs for easy part removal
• Meets MIL and JEDEC specs
• Standoff controlled with unique wedge design that applies no pressure on the lockable micrometer
• Use in Fancort Hand or Air Press

Dedicated Tooling: Semi-Automated Systems

Higher volume requirements may call for some type of component handling during trim and form. Illustrated here is one custom system that uses a manual vacuum loader to remove parts from a matrix tray, load them into the tool, fire the tool manually or automatically, and unload finished parts into the tray. For additional information, contact us at the factory with your requirements.

Spec. Sheet fot Quad and Flat Packs

The following is a guide to help you fill out our quad pack and flat pack spec sheets. Please furnish the parameters listed below and call us if you need further information or technical assistance.

A. Stand-Off/PCB Offset Height - This dimension can vary and may sometimes include clearance for a heat sink. On the forming tool, this dimension is adjustable with a micrometer. Usual tolerance is ± .002.

B. Shoulder - This is only noted on our Universal spec sheets. It is the distance from the body of the device to thevertical tangent of the first bend, "G." This dimension is critical and size range depends on body type and lead thickness. For instance, the "B" dimension for ceramic parts can be as small as .030" and for plastic parts could be as low as .010". Metal Glass Seal parts will require a substantially larger "B" dimension. A suitable should dimension is often a judgement call based on therequired footprint vs. part size and type.

C. Lead Material Thickness - This is the total thickness including plating (and tinning, if applicable). This is a very critical dimension and enormously effects spring-back, foot position, burnish (on the leg) and your tip-to-tip "D" tolerance. The smaller range the better. Usual tolerance here is ± .002" (ideal is .001"±).

D. Tip-to-Tip - This is the required size of the device after form and trim. This dimension includes spring back and cumulative tolerance. Usual tolerance here is ± .010".

E. Foot Option #1 - This is the total foot length that will encounter solder, measured from the tip to the virtical tangent. Tolerance here is ± .005". This dimension typically ranges from .030" to .060".

Foot Option #2 - This represents the JEDEC method of specifying this dimension. As is the case with Foot Option #1, tolerance is normally ± .005" and size range typically varies from .025" to .060".

F. Overall Body Thickness - This dimension should include covers and/or heat sinks. Significant variations in this dimension within part lots can cause unacceptable variations in the final "D" dimension. Please use or send us the manufacturers case drawing to eliminate confusion.

G. /H. Upper & Lower Radii - These, as a rule, should be 1 ½ to 2 x the maximum material thickness "C". A typical tolerance range for these values is +/004-.002 or slightly greater depending on the lead thickness tolerance. Please contact us if you have any questions.

J. Body Thickness - Vertical distance between the bottom of the lead as it exits the body and the bottom of the part body. (Refer to "F"). Specify a required tolerance.

L. Lead Width & Pitch - This is important to set up the tooling. We need dimensions for lead width, "L", and lead pitch.

M. Body Width - Specify a tolerance or maximum dimension.

N. Heat Sink Width - Specify a tolerance or maximum dimension.

Y. Body Length - Specify a tolerance or maximum dimension (Note: For two-sided flat packs only).

** Leads Per Side - Specify number. Also note required package orientation (Part ID# side up or down).

** Total Number of Leads - It's important to highlight if the part body is square or rectangular. Note: for rectangular parts, use dimension "X" and dimension "Y" on the quad sheet.

** Leads Tinned - It is important to note whether the leads have been tinned prior to forming. The "as measured" "C" dimension will thus include the tinning layer thickness.

**Lead Type - Fancort tools can be used with standard setups for flat leads. Round leads generally require more spring pressure and stepped pressure pads to reduce coining. The radius should be increased on round leads to 2 - 2 ½ x "C" and flatting within mil-spec (10%) should be expected. Please note the "B" dimension (shoulder) should be extended as much as possible. (The same as for a metal package).

** Toe Up or Down - Most customers using hot bar soldering want the toe angle to be 0° flat to 4° down. This dimension can be held fairly accurate if the "C" dimension is maintained ± .001". For customer using IR oven soldering, the typical foot position is 0° flat to 4 °toe up.

** Package Type -Specify whether the package is top exit, side exit or bottom exit
