PCB Mfg Aids

Connector Protectors - "U" or "C" shaped channels are rip cut from 18' lengths of square rectangular glass laminated epoxy tubes. The inside base width of the channel is established by the connector width and the connector height establishes the legs of the channel.

Box shaped connector protectors are short pieces of glass epoxy tubing cut to the connector height and closed on one end with a shoulder cut header plate. The 155C material has excellent mechanical strength, resistance to fluxes, solvents and the elevated preheat and soldering stages. Thickness is generally .030" which saves space over thicker molded boots and allows for a thermal air gap to further protect the connector. Ordering details in our Design Data Pamphlet and Mandrel List of open stock tools.

 

Gold Fingers Glove - Gloves are "U" shaped fiberglass laminated epoxy channels with .062" ID wide base to fit over the edge of standard circuit boards. Fingers from .250" to .765" long fully sheath edge mounted gold contacts. Channels up to 18" long are made in .030" thickness to provide positive production from the shock and impact of assembly tools. The very high short term heat distortion temperature and long term Class 155C rating plus its ability to meet UL94V-0 tests, enable the glass epoxy to withstand the harsh chemical and temperature environment of wave soldering.

With a minimum of 100 VPM dielectric, gloves are also used as Static Discharge guards to protect live contacts from nearby diode discharge. Spring tension enables guards to cling to the boards through many cycles.

 

PCB Stiffeners - Glass roving per MIL-60346B and epoxy resin 130C per MIL-R-9300 Type 1 and UL 94V-1 are pultrusion molded to produce 1/4" square solid epoxy rods with 150,000 PSI flex strength. Solid epoxy rods are bonded to boards, slotted for edge mounting, drilled for riveting, or fitted with #4-40 threaded inserts.

Glass epoxy PCB stiffeners are lighter than aluminum, with high dielectric strength they eliminate electrical shorting, and prevent warping during wave soldering. Pairs of slotted rods are bonded on opposite side walls of a glass epoxy housing to serve as card guides. Rods for .062" thick boards are slotted .070" + .010" - .000" wide x .125" plus or minus .010" deep, then cut to your specified length.

Sizes available are 1/8" x 1/4" , 1/4" x 1/4" , 1/4" x 5/16".

 

Board Carrier - Reusable fiberglass laminated epoxy gloves cover the gold contacts on circuit boards as well as providing a way to suspend the boards below the conveyor during wave solder.

The gloves are "U" shaped channels with a .062" wide base to fit over standard boards and with fingers up to .750" long to fully sheath the edge mounted gold contacts. An extra piece of material is molded to the back edge of the protector allowing the board to lay flush with wave solder machine belts.

Laminated fiberglass epoxy material has a very high resistance to impact, harsh chemicals, and high temperature environments of wave soldering and conformable coating operations.

Gold finger gloves are easily applied in long strip form with sufficient spring tension to cling to the board through many cycles resulting in significant labor and materials savings.

 

Board Stiffener - Reusable fiberglass laminated epoxy gloves mask the gold contacts on circuit boards as well as providing stiffness to the board during wave soldering.

The gloves are "U" shaped channels with a .062" wide base to fit over standard boards and with fingers up to .765" long to fully mask edge mounted gold contacts. The gloves are reinforced with a 1/4" square pultruded unidirectional glass epoxy rod along their length. With a flexural strength of 150,000 psi, these rods provide increased stiffness to the PCB to prevent warpage.

Fiberglass epoxy material has very high resistance to impact, harsh chemicals, and high temperature environments of wave soldering and conformable coating operations.

Gold fingers glove/board stiffeners are easily applied in long strip form with sufficient spring tension to cling to the board through many cycles resulting in significant labor and materials savings.
