- BIRD - 5-1357-3 - Connector, Electronics Solder Eyelet, Rivet/Eyelet/Terminal. Package of 100.
BIRD - 5-1357-3 Connector, Electronic Solder Eyelet, Rivet/Eyelet/Terminal.
Electronic eyelets are flanged tubular metal conductors inserted into a printed circuit board. They make electrical continuity between the circuitry on both sides of the board, and are an attachment point for soldering component leads.
Type: Solder.
Appears to be Silver Plated Brass (High thermal and electrical conductivity)
Metric Dimensions: Outside lip is 6.1mm OD, 2.9mm ID with a shaft 3.5mm round and 6.7mm tall under Lip.
Inch Dimensions: Outside lip is 0.240" OD, 0.114" ID with a shaft 0.138" round and 0.264" tall under Lip.
Applications: Secure High Current Electrical and Ground Connections or repairs to chassis and PWBs.
Chose the proper eyelet keeping the following in mind:
LUF The length of the eyelet barrel under the flange should be 0.020-0.035”/0.630-0.890mm greater than the thickness of PCB(this allows the for the right length after the flange is formed)
ID Eyelet inside diameter should be 0.003-0.020”/0.075-0.500mm greater than the component lead diameter for proper fit of the eyelet through-hole component lead.
FD The flange diameter should be sized so that it does not protrude out onto other pads or conductors in the vicinity
OD The clearance in the PCB hole should allow the eyelet to be inserted without undue force but, but should not exceed 0.125mm greater than the eyelet outside diameter.Additional Information: http://www.intl-eyelets.com/short_course_on_electronic_eyelets.htm

Hollow True Bakelite Tube/Rod.
Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is high resistance which make it a poor conductor of heat and electricity. Due to its hardness and strength it is widely used in switches, relays and connectors. Bakelite is little used in consumer products today due to the cost and complexity of its production and has become quite collectable in recent years.
Dimensions: 1/4" OD x 18" long, with an ID of 0.140".
Great project material. Widely used in electronics, power generation, antenna or various other industries. Insulate high voltage lines or cut to create high voltage stand-offs.
Industrial functional bakelite tubes for insulating, mounting, spacing electrical/electronic parts, wiring or assembles.
