Pulsed heat hot bar reflow soldering is a selective soldering process in which two solder plated parts are pressed together and heated to a temperature adequate to cause the solder to melt and flow, after which the parts are cooled to form a permanent electro-mechanical bond.

Pulsed heated soldering differs from traditional soldering because the reflow of solder is accomplished using a heating element called a “thermode” which is quickly heated and then cooled down for each connection resulting in strong joints.

Pressure is applied throughout the entire cycle resulting in precise positioning. It also makes the process suitable for parts that might otherwise disconnect during cool down. Hot bar reflow soldering is also a good choice for applications that require multiple connections to be made simultaneously. Hot bar reflow soldering processes are reproducible, quantifiable, and traceable to quality standards such as ISO / NIST. Hot Bar reflow soldering is safe, highly operator-independent and easy to automate.

ACF/ Heat-Seal Bonding

Heat seal bonding – also called ACF bonding – is the process of creating electrical conductive adhesive bonds between flexible and rigid circuit boards, glass panel displays and flex foils with very fine pitch (<30 micron). The essential characteristics of this process are heating and cooling of the adhesive under pressure.

Heatstaking

Heatstaking is a method of joining two or more parts, where at least one is made out of plastic. The bond is made by partially de-forming the plastic part to fix the other. Heatstaking is the most efficient way to bond metal to plastic, and is commonly used in high volume/low cost applications in the automotive, telecom and appliance industries. The process works by heating the plastic to a temperature above the glass transition temperature via the use of super-heated air or a thermode, and then applying pressure in order to deform it and create the stake. The plastic is then cooled down again – under constant pressure – below the glass transition temperature, ensuring good fixation of the parts. This cooling can be done with compressed air if using a thermode, or with a cold, preformed tool if super-heated air is used.

AMADA WELD TECH offers a full line of reflow soldering power supplies, bonding heads for benchtop use or for integration or automation, thermodes, and both standard and custom systems for reflow soldering, heat seal bonding and heat staking.

The UF Series 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.

UF-4000A is available as a standard reflow soldering unit with a built-in transformer, or as a remote unit (UF-R4000A) with a smaller control unit and separate remote transformer– an ideal option for many automation installations.

Laser cutting and laser micromachining are non-contact processes which utilize a laser for micro drilling, micro milling, micromachining, micro patterning, micro scribing and ablation for industrial applications. The cut and feature edges are of high quality with little no burring, low surface roughness and dimensional accuracy.

The laser micro cutting process works by directing the laser beam through a co-axial gas nozzle to the workpiece. The laser melts a thin filament of material according to power and part conduction, the pressure of the coaxial assist gas then removes this molten filament through the underside of the cut. This process is repeated as the laser moves across the workpiece. According to cut conditions the periodic removal of material can sometimes be seen as “striation” lines running from the top to the bottom of the cut edge. This is a single pass processing technique that can create single sided features and asymmetrical features with very small internal radii.

Lasers welders produce a beam of high intensity light which, when focused into a single spot, provide a concentrated heat source, allowing narrow deep welds and fast welding speeds. The process is frequently used in high volume applications such as in the automotive and medical industries. Laser welding is a non-contact process which requires access to the weld zone from only one side of the parts being welded. There are many joint geometries that can be welded, but there must be a close fit-up at the joint interfaces, which makes tooling a key aspect for laser welding success.

Three types of welds can be achieved with a laser welder: conduction, transition/keyhole and penetration or full keyhole. Conduction welds are performed at low power, resulting in wide, shallow weld nuggets. Transition/keyhole welds utilize medium power density and result in a deeper weld nugget typically with a width to depth ratio of around 1. Penetration or full keyhole welds are resultant of direct power delivery into the material via the keyhole resulting in deep, narrow welds with width to depth ration typically between 3-10.

Laser Spot Welding

Laser spot welding is a process which uses a laser welder to create a single weld spot to join metals together. Laser welders are capable of delivering a precise pulse of ligh with accurate, repeatable power, energy and duration. When the laser pulse is focused into one place – a small spot – (adjustable anywhere from approximately 0.02 to 1.0 mm (0.001”-0.040”) in diameter) on the part, the power density is sufficient to cause rapid melting to create the weld. The high power density enables efficient absorption of the laser by creating the “keyhole effect.” As the pulse ends, the liquified metal resolidifies and creates a small spot weld. This entire process happens in just a few milliseconds.

Laser Seam Welding

In laser seam welding, the part to be welded is moved or rotated under the focus head allowing laser spot welds to overlap or for a CW fiber laser provide sufficient penetration. Key parameters for pulsed laser seam welding are the pulse repetition rate, measured in pulses per second (Hz), and the linear part travel rate or welding speed and focused spot diameter. For CW fiber lasers the power and spot size, and position of focus are key parameters. With each of the lasers these parameters are precisely controlled to provide the exact weld needed, whether for mechanical strength or a level of hermetic sealing.

Pulsed Nd:YAG and fiber, and CW fiber laser welders can join a wide range of metals, including mild and stainless steel, nickel and nickel alloys, titanium, aluminum, and copper and copper alloys. Dissimilar metal welding is also possible between a number of these materials.

AMADA’s WL-100A is a highly configurable, compact unit designed for lean manufacturing and offering the widest range of marking capability in its class.

Transistor direct current power supplies (also called “Linear DC”) produce much the same results as the high frequency inverter by using a high number of power transistors as the direct energy source. This technology provides clean, square wave forms with extremely fast rise time. Used primarily in constant voltage feedback control, transistor DC power supplies are effective in thin foils and fine wire welding applications and for extremely short welds.

The UB-4000A Linear DC welding control is ideal for applications which require exceptional control, fast rise times, and high quality throughput. UB-4000A requires only single phase input power and can output up to 4000 amps. Ultra-fast rise times permit short overall weld times, resulting in less part deformation and stronger welds. This is extremely important when welding heat sensitive parts such as battery cells or sensitive electronic devices.

UB-500A (5-500 amps), and UB-1500A (15- 1500 amps) are Linear DC controls with feedback modes designed to adapt to part and process variables. These power supplies should be used for smaller applications where closed-loop feedback control and fast response times are required. Safety critical applications such as those found in the medical and automotive markets will benefit from UB-500A’s precision low energy control.

This can eliminate the Peltier effect (polarity effect) and provide uniform nugget diameters on series welding.

Two-channel type

Two weld heads can be controlled by one power supply. It contributes to cost and space savings.
