Hot Bar Soldering Flex Circuits

Hot bar soldering is extremely effective in bonding components and parts that are dissimilar and difficult to unite.

Hot bar soldering flex circuits.

The primary tools include. There are a variety of methods for soldering these. The required process energy is supplied by a thermode also know as a hot bar. Hot bar reflow soldering is achieved when two pre fluxed solder or adhesive coated parts are heated causing the solder to melt flow and then.

Fine pitch sm devices. Hot bar reflow soldering bonding fundamentals technical articles and whitepapers blogs videos training information and more. Exposed lead both sides of the polyimide material are removed leaving the traces free of insulation. Tab to pcb hsc to lcd or tab.

This allows the thermode hot bar to contact the traces directly conducting heat to the parts and creating the bond. Mobile electronics such as telecommunications equipment as well as the electronics in motor vehicles require increasing packing density and thus arrangement of the circuits in multiple layers. The benefits of hot bar reflow soldering. Design tips for successful hot bar reflow soldering.

Uniflow 4 provides targeted heating and precision temperature control for hot bar soldering applications such as the connection of flexible circuits ribbon cables wires smt components single or dual sided edge connectors and thermocompression bonding of gold ribbon. Flex circuit to pcb. Process also conserves vertical height of assemblies. Ribbon cable to pcb.

Edge connectors to pcb. Applications of hot bar reflow soldering. Typical hot bar reflow soldering applications include flex circuits ribbon cables wires flex to pcb flex to lcd and thermocompression bonding of gold ribbon as found in the telecommunications computer automotive display industries and more. Pulsed heat thermode hot bar soldering is a joining technology where two pre tinned parts are heated to the melting point of the tin.

2 customized soldering head press all of the soldering joints of parts on pcb to solder it simultaneously by heating them to a temperature it greatly improve soldering efficiency. Of soldering the sensor to the flex circuit. Hot bar reflow soldering systems. 1 lead free compatible hot bar process of flex to pcb can replace more costly flex printed circuits and save the cost of pcb connectors.

Fast temperature ramp up and cool down. The connection of the layers are favorably produced with flexible circuit carriers and or foil connectors these connections are prepared mostly by hot b ar reflow soldering. Manncorp now has the solution to these tough soldering challenges. The joining technology results in a permanent electro mechanical joint.

3 layouts for hot bar reflow soldering. Flex carriers and foil connectors. Hot bar soldering systems. Accurate positioning of the parts.

The three most common flex circuit termination designs for successful pulse heated reflow soldering are exposed lead single sided and open windowed choose the one that best suits your design and manufacturing needs.
