Hot Bar Soldering Equipment – A Variety Of Tips For Purchasing a Soldering Robot.

Pulsed heated hot bar reflow soldering is soldering robot in which two solder plated parts are pressed together and heated to some temperature adequate to cause the solder to melt and flow, and after that the various components are cooled to form a permanent electro-mechanical bond. Pulsed heated soldering is different from traditional soldering because the reflow of solder is accomplished utilizing a heating element known as a “thermode” that is quickly heated then cooled off for every single connection leading to strong joints. Pressure is used through the entire entire cycle causing precise positioning. Furthermore, it definitely makes the process appropriate for parts which may otherwise disconnect during cool off. Hot bar reflow soldering is yet another good option for applications that require multiple connections to become made simultaneously; up to 200 leads or wires could be connected in one process cycle. Hot bar reflow soldering processes are reproducible, quantifiable, and traceable to quality standards for example ISO / NIST. Hot Bar reflow soldering is safe, highly operator-independent as well as simple to automate.

Heat seal bonding – also called ACF bonding – is the method 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 pulse heat bonding machine are heating and cooling of the adhesive under pressure.

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 16dexgpky 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.
