Hot Bar Reflow Soldering & Bonding

connections to be made simultaneously; up to 200 leads or wires can be connected in a single process cycle. 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.
