PBS Hot Bar Soldering Features
- Lead-free compatible hot bar process of flex-to-PCB can replace more costly Flex-Printed Circuits and save the cost of PCB connectors. Process also conserves vertical height of assemblies.
- Other applications: Heat seal bonding and conductive adhesive bonding.
- Real time temperature profiling displayed on touch screen. Process time is only 12 to 15 seconds.
- System pressure, temperature, heat-up, reflow and cool-down are programmable.
- High-speed PID controls temperature output for faster processing.
- Vision system with CCD camera and monitor is low-cost option.
- Custom fixtures and thermodes for all applications included. (One set of thermodes plus one fixture set for PBS212 and two fixture sets for PBS213)

Manncorp's PBS hot bar system programs all elements of the soldering profile, including pressure, temperature, heat-up and cool-down times. The processing cycle, completed in just 12 to 15 seconds, begins by loading the PCB and flex into the fixture and fluxing the joint area. After the fixture is positioned into the work area, the cylinder lightly pushes the thermode against the parts, and once contact is made, it quickly heats up using high-speed PID to control temperature output. Peak reflow temperature is reached in 2 seconds or less.
When solder reflows, heating automatically stops and cool-down begins, lasting approximately 2 seconds, with topside-originating air assuring cooling uniformity. When solder has solidified, the cylinder automatically lifts to release the now-bonded parts.
Two versions of the PBS Systems are offered. PBS212 is a shuttle in/out processor, while PBS213 is a rotary machine that presents completed assemblies on a rotating axis for loading/unloading by operator. Both machines, which are lead-free compatible, offer vision systems with CCD camera and monitor as a low-cost option.
CCD Alignment Modules / Interposer (Option)
Adjustable fixture and single or dual CCD cameras are mounted on the frame for fine pitch magnification.
The Interposer protects the components during bonding process to improve the bonding strength. The Modules uses Polyimid (Kapton) tape or Silicon tape which is mounted on the Gantry. Feeding length and number of cycles before next feeding are programmable with sensor-controlled dual motors. System design prevents flux contamination on the Thermode.
Other PBS's features:
Heating profiles setup and adjustments are touch screen controlled. PID temperatures are attained quickly.
During the soldering/bonding cycle, temperature profile, time and pressure are displayed on the LCD screen in real time.
Digital control for the soldering/bonding pressure, is adjustable from 30 to 500N.
Titanium Flop-up Thermode Design
PBS bonding systems feature "Flop-up Thermode" which ensures ultra-fast heating and cooling cycle. Forced air-cooling further speeds up the operating cycle. Special Ti-alloy Thermode maintains co-planarity and withstands heating cycle deformation that is essential for the bonding process. This thermode also prevents voltage drop as current flows through the thermode from front-to-back instead of left-to-right, preventing damage to sensitive components during soldering.
