Radial Taping Specifications

Receiving Client Devices

• Measure the body diameter (or thickness) of the component and assign it a class as per “Radial Specification Sheet,” OX3.5WI-089”. Also determine the device type, lead type (Straight or Formed), and Height to Seating Plane.  Record this information on the packing list.  Refer to EIA 468 and the Radial Specification Sheet in their latest revisions.
• Check if OX3 has the drums required to tape this part as per the Radial Specification Sheet. If not, put the parts on hold and create a Customer Disposition Form.  Make two copies; one to go with the parts and one to go to the Sales Department.

Determining Class of Radial Component:

All Radial lead devices are taped in accordance with EIA STD-468C up to the Reaffirmation Notice or October 18, 2013.  For purposes of pricing, use of proper materials, and production throughput, we have identified five general classes of radial product in order to cover the full spectrum of radial leaded device sizes.  Follow Table “A” to determine classification for a radial leaded device.  For pricing, contact Sales@ox3.com.

Classify as “Extra Thick” all components that measure 0.300” or greater in lead spacing, regardless of the body thickness / diameter since these will skip a hole on the paper tape with 12.70mm spacing.

Notes:

1. Tape straight leaded radial components at 18 to 20mm unless NSW states otherwise (S-19).
2. Tape formed radial components at 15.5 to 16.5mm unless NSW states otherwise (F-16).

 In order to minimize space and shift in packaging, follow Table “B” to determine core length to use when reeling:

Running Radial Components:

• The Machine Operator gets an “OX3 Axial, Radial & Forming Line Traveler,” OX3.5FM-013, staples it to the paperwork, goes to the machine assigned, and fills out the line traveler, (except the quantity). The parts may come in pre-counted bags.  The machine operator must go through the paperwork for any SOWs or customer specifications and follow them.  When in doubt ask the production supervisor or group leader.  If the workstation is not clean, immediately notify the supervisor.
• If the machine is not heated-up, wait until it does and then proceed to set up the machine.
• Fill in the “Production Log,” OX3.5FM-018 on the computer. If the machine is not set-up for this order, do so.  If the operator has problems setting-up the machine, call the production supervisor or group leader for assistance.  Use a vernier caliper if needed.
• Check the sales order for any specific instructions. The customer may have requested only a certain number of parts per reel.  If that is case, then follow it.  Otherwise, ask the production supervisor or group leader.
• Follow the instructions on OX3.5WI-089, “Radial Specification Sheet.”
• Before taping, make a trailer of at least 12 sprocket holes without any parts. Start taping the parts.  Follow EIA 468 standards and, if needed, refer to them.  Check for the orientation of parts.  Tape with positive or anode lead towards the bottom.  After taping 25-30 parts, call the QC Inspector over to conduct an In-Process Inspection.  If the inspection passes, continue with running the parts.  If the dimensions are incorrect, call the supervisor and correct the problem.  In either case, attach the “Radial In-Process Inspection Form,” OX3.7FM-028 to the paperwork.  Make sure that there are no empty spaces on the reel.  After all parts are done or the reel is almost full, stop taping the parts.  If possible, enter the count on the traveler.  Tape another leader of at least 12 sprocket holes without any parts.  Remove the reel from the machine.  If the quantity is different than the one mentioned on sales order (SO#), put the new quantity on the traveler, and inform the production supervisor.  Stick a small piece of tape on the same side and write down the SO# and the quantity on the reel.

Apply transverse masking tape across the gap between reel flanges in order to make them sturdier during shipment.
