Each has generally a rectangular configuration with supporting surfaces along inner peripheral. A plurality of wafers each is supportively received in the section along its bottom edges by the supporting surfaces. Each wafer includes a plurality of contact terminals each arranged in the wafer. Each contact terminal has a tail portion extending beyond the bottom surface. A pick-up cap is properly attached to the supporting frame to position the wafer. ## Claims ### Claim 1 An electrical connector assembly, comprising: a supporting frame defining different sections arranged adjacent to each other, and a number of supporting surfaces extending from the inner edges of each section, the supporting frame having a bottom surface; a plurality of wafers each supportively received in the section along its bottom edges by the supporting surfaces, each wafer including a plurality of contact terminals each arranged in the wafer, each contact terminal having a tail portion; and a pick-up cap properly attached to the supporting frame to position the wafer. ### Claim 2 (depends on 1) The assembly as recited in claim 1, wherein each section includes an inner rim serving as the supporting surface. ### Claim 3 (depends on 1) The electrical connector assembly as recited in claim 1, wherein each of the contact terminals is adapted for being attached with a solder ball. ### Claim 4 (depends on 1) The electrical connector assembly as recited in claim 1, wherein the pick-up cap includes hooks releaseably secured to the supporting frame. ### Claim 5 (depends on 1) The electrical connector assembly as recited in claim 1, wherein each section has a general rectangular configuration. ### Claim 6 (depends on 5) The electrical connector assembly as recited in claim 5, wherein each section is perpendicular to an adjacent section. ### Claim 7 (depends on 6) The electrical connector assembly as recited in claim 6, wherein there are four sections and jointly defines a central opening therebetween. ### Claim 8 An electrical connector assembly comprising: a printed circuit board; a supporting frame defining different receiving sections arranged adjacent to each other, each of said receiving sections including upward supporting ridges and a bottom surface; and a plurality of wafers each supportively received in the corresponding receiving section by the supporting ridges, each wafer carrying a plurality of contact terminals each arranged in the wafer an having a tail portion, and the wafers are respectively floatable in the corresponding receiving sections before the terminals are soldered to the printed circuit board; wherein the tail portions of said terminals are soldered upon and secured to the printed circuit board. ### Claim 9 (canceled) ### Claim 10 (depends on 8) The assembly as claimed in claim 8, wherein the wafers are allowed to be removed away from the frame before said terminals are soldered to the printed circuit board. ### Claim 11 (depends on 8) The assembly as claimed in claim 8, further including a pick up cap which retainably sits upon the frame and the associated wafers to the printed circuit board under a condition that the pick up cap prevents the upward withdrawal of the wafer from the frame. ### Claim 12 (depends on 8) The assembly as claimed in claim 8, wherein the frame defines a retention post inserted into the a hole in the printed circuit board during assembling. ### Claim 13 (depends on 11) The assembly as claimed in claim 11, wherein a dimension of the frame is similar to that of the pick up cap. ### Claim 14 An electrical connector assembly comprising: a printed circuit board; a supporting frame defining different receiving sections arranged adjacent to each other, each of said receiving sections including upward supporting ridges essentially commonly fully circumscribing the corresponding receiving section, and a bottom surface which confronts the printed circuit board; and a plurality of wafers each supportively received in the corresponding receiving section by the supporting ridges, each wafer carrying a plurality of contact terminals each arranged in the wafer an having a tail portion; wherein the tail portions of said terminals are soldered upon and secured to the printed circuit board; wherein the frame defines a retention section coupled to the printed circuit board. ### Claim 15 (depends on 14) The assembly as claimed in claim 14, wherein the wafers are floatable in the corresponding receiving section before the terminals are soldered to the printed circuit board. ### Claim 16 (depends on 14) The assembly as claimed in claim 14, wherein the wafers are not allowed to be downwardly but upwardly withdrawn from the corresponding receiving section. ### Claim 17 (depends on 14) The assembly as claimed in claim 14, wherein the upward supporting ridges in each of the receiving sections provides one continue surface. ### Claim 18 (depends on 14) The assembly as claimed in claim 14, wherein the upward supporting ridges in each of the receiving sections is defined spaced serially in an inner rim of the receiving sections. ### Claim 19 (depends on 11) The assembly as claimed in claim 11, wherein the wafers are circumferentially compliantly received in the corresponding receiving sections, respectively. ### Claim 20 (depends on 14) The assembly as claimed in claim 14, wherein the wafers are circumferentially compliantly received in the corresponding receiving sections, respectively. ### Claim 21 (depends on 16) The assembly as claimed in claim 16, further including a pick up cap assembled upon the frame defining a plate for not only suction by a nozzle during mounting the frame and the associated wafers to the printed circuit board, but also preventing upward withdrawal of the wafers away from the frame before mounting the frame and the associated wafers to the printed circuit board.
