Hot bar soldering flex circuits.

1 a standard soldering iron 2 hot plate 3 standard solder 4 solder paste no clean use either eutectic sn63pb37 e g. The joining technology results in a permanent electro mechanical joint. Fast temperature ramp up and cool down. Hot bar reflow soldering bonding fundamentals technical articles and whitepapers blogs videos training information and more.

Accurate positioning of the parts. Flex circuit to pcb. Hot bar soldering systems. 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.

The benefits of hot bar reflow soldering. Process also conserves vertical height of assemblies. Typical examples of applications are connecting flex foils to printed circuit boards small wires small coax cables and very light or small components. Applications of hot bar reflow soldering.

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. Manncorp now has the solution to these tough soldering challenges. 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. 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.

Edge connectors to pcb. Tab to pcb hsc to lcd or tab. Pulsed heat thermode hot bar soldering is a joining technology where two pre tinned parts are heated to the melting point of the tin. 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. 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. Hot bar soldering is extremely effective in bonding components and parts that are dissimilar and difficult to unite. 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.

There are a variety of methods for soldering these. The required process energy is supplied by a thermode also know as a hot bar. Of soldering the sensor to the flex circuit. Ribbon cable to pcb.

Exposed lead both sides of the polyimide material are removed leaving the traces free of insulation. Hot bar reflow soldering systems. 3 layouts for hot bar reflow soldering. Flex carriers and foil connectors.

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.
