In the allocated cap area, bubble caps are generally arranged on equilateral triangular pitch. Number of caps fixed on a plate is with a __________________?
Correct answer: B. Either A. or B.
- A. Clearance of 25-75 mm
- B. Either A. or B.
- C. Cap pitch of 1.3-2 times the cap diameter
- D. Neither A. nor B.
Explanation
Bubble-cap layouts commonly use a clearance of roughly 25 to 75 mm and a pitch around 1.3 to 2 times the cap diameter. Both A and B describe accepted spacing guidance.
