Summary of the invention
Can not be when the present invention mainly solves the integrated circuit (IC) chip encapsulation to the integrated once more technical problem of former chip circuit, a kind of simple and easy integrated method outside the core of also implementing when encapsulation is provided, the resource in the former chip circuit of recombinating, or change or expanded circuit function, reduce former integrated circuit volume, (or reduce former integrated circuit take up space) shortens the new lsi development cycle, save the simple new integrated circuit of development small lot and pay the great number cost, be badly in need of to satisfy Application Design fast.
The present invention is that to solve the problems of the technologies described above the technical scheme of being taked (method) as follows:
(1) the new nead frame of the design layout uniqueness different with standard, wherein base plate and pin, or there is access bridge to intert wherein between pin and the pin, access bridge wire (line) risen the same with base plate passed through the transfer transitional function, do not draw outside the encapsulation, as embodiment 1,2, used new frame in 3, four pins 5 are wherein arranged, 6,7,8 side by side in the straight long limit of base plate 10, there are symmetrical two access bridges 11 on other three limits of base plate 10,12 armfuls around, at access bridge 11,12 outsides have two pins 2 again, 3 whole process are held up with both hands, at two pins 2,3 outsides have two pins 1 again, 4 whole process are followed and are escorted, can be fit to paste IC chip 9 and discrete electronic device on the base plate 10 simultaneously, pin, some loose position on the access bridge, also just in time be fit to paste discrete electronic device or simple chip, pin, access bridge, backplane placement, adapt to the freely direct or leap connection of wire easily, avoid wire in the middle of chip, to cross over;
(2) utilizing the layout advantage of unique new frame, need to merge for some end points (bond pad) of circumferentially-spaced on discrete device and the chip 9 and draw, is with wire directly or cross a certain suitable pin or access bridge and merge and connect; Need to merge for two or more end points (bond pad) of circumferentially-spaced on the chip but do not draw, directly or cross over and be connected on a certain suitable access bridge or base plate with wire; For the line on chip and the discrete device, can directly connect or indirect utilization pin, access bridge, base plate transition connect;
(3) utilize the existing standard framework, connect the end points (bond pad) that merges on the IC chip 9, realize that core is outer simple and easy integrated, its concrete grammar is, for adjacent side on the chip or opposite side isolated some need merge the end points (bond pad) of connection, be connected on certain same pin from the 9 middle conveniences leaps of IC chip with wire, realize that great-leap-forward merges connection; For on the chip with isolated some end points that need merge (bond pad) on one side, with wire directly or cross over and be connected on certain same pin, realize merging and connect; For some end points that need merge (bond pad) of circumferentially-spaced on the chip, be connected on the base plate 10 with wire nearby separately earlier, be connected to a certain pin with wire from base plate 10 again, utilize base plate to make terminal, realize passing through merging and connect; For some key discrete device or companion chip in the application circuit, stick on the suitable position of base plate or pin or access bridge earlier, connect with wire again.
The beneficial effect that the present invention produced is: easily that the pin position is many external end points of IC chip circuit (bond pad), before encapsulation, merge integrated once more, become the few new integrated circuit in pin position, make in the former chip circuit resource obtain reorganization or expansion, easily make former chip become one the complicated slightly new integrated circuit of new function or function is arranged, reduce former integrated circuit volume (or reduce former integrated circuit take up space), shorten the new lsi development cycle, save the simple new integrated circuit of development small lot and pay the great number cost, be badly in need of to satisfy Application Design fast.
