Description
Technical field:
What the utility model related to chip plants ball instrument, plants ball instrument in particular to a kind of for bga chip.
Background technology:
Along with the progress of technology, chip integration improves constantly, and I/O pin number sharply increases, and power consumption also increases thereupon, also stricter to the requirement of integrated antenna package.In order to the needs of satisfied development, BGA package starts to be applied to producing, BGA (English BallGridArrayPackage) i.e. BGA Package technology, the I/O terminal of BGA package is distributed in below encapsulation with circular or column solder joint by array format, and be arranged in the pattern that is similar to grid, this technology has the following advantages: although I/O number of pins increases, and the distance between pin is large, improves rate of finished products; Although the power consumption of BGA increases, be the welding of control collapsed chip method due to what adopt, thus can electric heating property be improved; Signal transmission delay is little, adapts to frequency and greatly improves; Assemble available coplanar welding, reliability improves greatly.Therefore BGA is the optimal selection of the high density such as CPU, mainboard south, north bridge chips, high-performance, many pin package, and a lot of chip device producer used, and the chip of BGA package is also just more and more universal.
Because BGA pin mostly is stanniferous material, carrying out in circuit board group process of assembling, device is because of through high-temperature soldering, and the scolding tin on device can melt, and is welded together with the line scan pickup coil side on circuit board, if when BGA device needs are reprocessed and are disassembled from circuit board, because pin material at high temperature melts distortion, after device disassembles, the pin of BGA just becomes all in tumble shape, at this moment bga chip cannot use, and therefore chip needs again to implant new solder ball.
Existing BGA plants ball technique and usually adopts steel net template to carry out, and disclosed in Chinese utility model patent CN102881599A, BGA plants ball technique, steel mesh is installed to and printing machine carries out contraposition fixes, and tin cream is coated onto on steel mesh; Several BGA are contained on carrier, and carrier is installed on printing machine, steel mesh is overlapped with carrier and carries out paste solder printing; After being completed for printing, check whether the tin cream on each BGA pad prints evenly, after confirming printing OK, be put into Reflow Soldering baking, complete and plant ball.Following shortcoming is there is: (1) needs the array way of steel net template and chip, the size of soldered ball and spacing one_to_one corresponding, poor universality in above-mentioned technique; (2) steel net template surrounding needs with cushion block frame high, makes it keep accurate distance, complex operation with the BGA device of printed scaling powder or soldering paste, needs operating personnel to have the operation skill of consummation; (3) due to the thickness of different chip and not of uniform size, what have also needs at the enterprising line operate of Rework station, and therefore, above-mentioned technique is not suitable for the unified maintenance of various chip.
As can be seen here, existing BGA plants ball technique poor universality, complex operation, is not suitable for the unified maintenance of various chip.
For solving the problems of the technologies described above, application number be the utility model of CN201420481106.3 disclose a kind of bga chip plant ball instrument, chip mounting table comprises workbench and is located at the cushion block of worktable upper surface, and cushion block is used for fixing bga chip; Plant the steel net template that ball template comprises upper and lower clamping plate and is folded between upper and lower clamping plate, the center of upper and lower clamping plate is provided with the through hole of up/down perforation, upper and lower clamping plate are provided with the through screwed hole of many groups around through hole, are wherein screwed with adjusting bolt in one group of screwed hole.Above-mentioned utility model utilizes adjusting bolt can regulate the distance of steel net template and bga chip to be processed, and steel net template is provided with different size, mesh array number can cover the number of arrays of most of chip, therefore can be used for the maintenance of most of chip, not by number of pins and the thickness limits of chip, manufacture simple, with low cost, highly versatile.
