Why is it called Focused Infrared and how is it different from normal IR?
PDR's infrared technology is not like any other IR system on
the market. PDR's IR technology is different, we use short wave IR and project
the light energy through a lens unit to create a Visible Focused IR Beam. It is called
Focused IR because we are focusing the IR energy through the PDR lens unit and therefore creating a
focusable and size adjustable heating spot/area to perform rework. Other competitive IR technologies use Medium wave IR
for the top heater, which is what PDR uses to preheat the PCB from underneath. Standard Non visible/Non Focusable IR Systems usually
look like a standard heating panel and are not visible to the eye leading to guess work as to what is actually being heated.

How does PDR's Focused IR work?
In principle a component is subjected to a ‘micro oven’ environment, being carefully heated to reflow from above and below. Focused IR is generated from a 150w tungsten-halogen lamp. An IR spot is projected through a series of special lenses and ...Can you rework reflective components with Focused IR?
The short answer, Yes we can. PDR has solved the biggest myth in BGA/SMD Rework by a simple roll of Thermoactive tape. As IR reflects of shiny surfaces, we are unable to heat the component efficiently on its own. To solve this, we use a black ...What are the advantages of PDR's focused IR over a Convection Rework System?
•Focused IR heating process - gentle, effective and instantly/precisely controllable, producing an ultra-high yield. •No nozzles, focus hoods, tooling or shields - an iris adjuster precisely sets the IR spot size from Ø4 - Ø70mm. •No interference ...Can the IR beam be square?
PDR prides itself on how easy our systems are to use, and the fact that PDR Focused IR eliminates the need for Air Nozzles. This includes PDR's industry leading adjustable iris where, with one motion, you can change the heating spot from large to ...Is PDR's IR Technology Safe? Do we need eye protection?
Tests Extensive tests have been conducted covering both Electrical and Infra-Red safety aspects on all of PDR's products. The tests were administered by a National Physical Laboratory approved establishment: ERA based at Leatherhead, Surrey, ...
