The Weller WBHS is a PCB Holder with a Tool Holder that is designed for use with the HAP3 and WHA3000P. The WBHS holds circuit boards up to 12.2in x 12.6in(310mm x 320mm). Precision glides allow a board to be precisely positioned and secured at any point along the X and Y axis. The WBHS accommodates both single and double sided boards,and it holds PCBs totally flat for added precision and repeatability. A smooth-acting lever raises and lowers the tool precisely onto the component 1.4in.(35mm) along the Z axis. The WBHS includes a tool holder that positions a hot air pencil perpendicular to the PCB during use.
