Does anyone know of a surface-mount component that could work as an Infrared Radiation barrier?

I have a PCB design that uses an infrared proximity detector in the form of an IR LED and an IR transistor placed with about 10 mm spacing between them. Now the problem has arisen that I need some sort of physical barrier between them to prevent crosstalk and false proximity detections.
  • Try SMD 0.1″ headers. Pick & Place and wave soldering are compatible, but these need a minimum of 3 pins due to the alternating SMD feet to keep them standing before the solder holds them on.
  • Switch to an transistoror diode pair that already comes with a molded body, unless those don’t exist in SMD.

What Others Are Asking

Does each process have its own PCB or there is just one?

To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?

What are possible solutions to PCB warpage problems?

My PCB manufacturer just informed me that he is facing PCB warpage issue in my simple, single sided, copper poured PCB. He says to avoid this issue he suggests to add a dummy copper patch by keeping 3mm copper clearance from all sides. Can somebody tell me what leads to this issue and what are possible solutions to this problem ?

Is it ok to call all the chips with alphanumeric labels BGA (ball grid array)?

Some ICs have their pins labelled only with numerical values and some use alphanumeric labels. I want to know what is the correct naming term for these cases.
Is it ok to call all the chips with alphanumeric labels BGA (ball grid array)? And for chips with only numeric pin labels the chip should be called DIL (dual in line)?
