Golf club heads and methods to manufacture golf club heads
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. The front portion may have a face portion. A rear surface of the face portion may have a plurality of face regions arranged in a plurality of rows and columns forming a grid. The plurality of face regions may have differing thicknesses to control characteristic time (CT) across the face portion. Other examples and embodiments may be described and claimed.

7. A golf club head as defined in claim 1 , wherein the first row of face regions comprises at least four face regions.
8. A golf club head comprising:
a body portion comprising a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion, the front portion comprising:
a face portion having a front surface, a rear surface, a rear center point on the rear surface, and a grid of face regions formed in the rear surface, the grid of face regions comprising:
a first plurality of face regions forming a first column of face regions between the rear center point and the heel portion; and
a second plurality of face regions forming a second column of face regions between the rear center point and the toe portion;
wherein a first face region in the first column of face regions has a first average thickness and a second face region in the second column of face regions has a second average thickness.
9. A golf club head as defined in claim 8 , wherein the first average thickness is greater than the second average thickness.
10. A golf club head as defined in claim 8 , wherein the second average thickness is greater than the first average thickness.
11. A golf club head as defined in claim 8 , further comprising:
a third plurality of face regions forming a third column of face regions above the rear center point and above the first column of face regions; and
a fourth plurality of face regions forming a fourth column of face regions below the rear center point and below the second column of face regions.
12. A golf club head as defined in claim 8 , wherein the first column includes at least three face regions.
13. A golf club head as defined in claim 8 , wherein the first column has at least five face regions.
14. A golf club head as defined in claim 8 , wherein the first plurality of face regions each have an average thickness between about 2.5 mm and 3.7 mm.
15. A golf club head comprising:
a body portion comprising a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion, the front portion comprising:
a face portion having a front surface, a rear surface, a rear center point on the rear surface; and a grid of face regions formed in the rear surface, the grid of face regions comprising:
a first plurality of face regions forming a first row of face regions above the rear center point;
a second plurality of face regions forming a second row of face regions below the rear center point;
a third plurality of face regions forming a third row of face regions above the rear center point and above the first row of face regions; and
a fourth plurality of face regions forming a fourth row of face regions below the rear center point and below the second row of face regions,
wherein a first face region in the first row of face regions has a first average thickness, a second face region in the second row of face regions has a second average thickness, a third face region in the third row of face regions has a third average thickness, and a fourth face region in the fourth row of face regions has a fourth average thickness.
16. A golf club head as defined in claim 15 , wherein the first average thickness is greater than the second average thickness, and the third average thickness is greater than the fourth average thickness.
17. A golf club head as defined in claim 15 , wherein the first average thickness is less than the second average thickness, and the third average thickness is less than the fourth average thickness.
18. A golf club head as defined in claim 15 , wherein the first average thickness is greater than the second average thickness, and the third average thickness is less than the fourth average thickness.
