The Alpha Series is excellent for both production R&D applications. The glovebox is available in two sizes: one for projection welding applications and the other for seam sealing or general industrial use. Straight-forward controls allow the operator to easily operate oven, vacuum and inert gas backfill controls.

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.

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.
