Pcb Board Stiffener
Fr4 g10 is the most common pcb stiffener material.
Pcb board stiffener. However for flex pcb circuits stiffeners are common and important requireed in many types of designs. If your flex circuit utilizing a fr4 stiffener it looks like a rigid flex pcb. The stiffener thickness can vary between 0 002 and 0 008 depending upon the flex circuit material construction. They add thickness to your board and impact both cost and manufacturing time.
If you need full custom design and production service orbel will ensure that your specific board stiffener and pcb stiffener bus bars needs are met. The pcb stiffener hole size should be larger than through hole. We use a high grade titanium to ensure the best strength from the stiffener. First pcb stiffener material.
Compufab has developed the universal stiffener an aluminum bar which can function as a mechanical pcb stiffener a heat transfer device or an electrical bus bar the universal stiffener fastens to a pcb with machine screws or rivets anywhere along the length of the bar. The thicker the pcb stiffener is the more support it will be able to offer. Fr4 stiffener in flex circuits. Typically when manufacturing your flex board and using pcb stiffeners you want to make the stiffener as thick as you possibly can given the design.
At orbel we handle every aspect of pcb board stiffener manufacturing from design and prototyping to production and delivery. Compufab s pcb stiffener is a lower cost alternative to machined fiberglass or machined metal pcb stiffeners. Also keep in mind that stiffeners require their own prepreg lamination cycle and certain stiffener materials require an additional lamination cycle as well. Flexible printed circuit boards also called flexible pcb or flex pcbs.
Fr4 can be the ccl of rigid pcb and it is the most common material applied for stiffeners in rigid flex and flex circuits. The thickness of the stiffener can range from 008 to 059. They add thickness to your board and impact both cost and manufacturing time. No flow prepreg is the preferred bonding material for joining flex and rigid materials.
Ascentec s titanium board stiffeners are designed to clamp onto the edges of the pcb in order to hold them properly on the conveyor. If you use zif stiffeners to thicken your board your board might end up being a lot harder than required. Stiffener stifferners are added rigidize areas of a flexible printed circuit fpc to strain relieve component attachment locations provide a firm surface for mounting or increase thickness of the circuit to correspond to the mechanical specifications e g. By the way some flex pcb factories also use polyimide and polyester pcb stiffener material we will introduce next.
