Unterstützungsschiene für HR500 mit 1 pin - Ersa 0HR504-01

Under 1600 W of infrared bottom heat a large board softens and sags in the middle. That is usually exactly where the rework component sits, and a warp of a few tenths of a millimetre is enough for the HR 500 placement with its 50 x 50 mm field of view to miss the pads. The 0HR504-01 support rail catches the board with one pin at that very point.

Benefits

• One pin, positioned precisely under the joint, so the support does not disturb the heat pattern of the 2 x 800 W bottom heater.
• Keeps the assembly in plane for the whole profile, which holds the distance to the 70 x 70 mm top heater constant.
• Genuine Ersa accessory for the HR 500, used in the existing board holder without modification.
• Mechanical support without adhesive or improvised fixtures, so the next board of the same type is set up the same way.

Applications

Removing and replacing BGA, QFN and large SMT parts on thin or wide assemblies where sag spoils the coplanarity of the solder balls. Rails with more pins can be combined when several support points are needed.
