Sensor package equipment
Technical field
The present invention relates to the semiconductor packaging field, particularly a kind of sensor package equipment.
Background technology
The multi-chip sensor is widely used in every field and product now, as being used for MEMS(Micro-Electro-Mechanical Systems, MEMS) etc. the sensor in product.Mainly comprised MCM(Multichip Module for this class multi-chip packaging of the fiber grating sensors mode now, multi-chip module) mode and SIP(System In a Package, system in package) mode etc., and these encapsulation are mainly to realize by means of artificial or the half artificial mode of production.
Realize by manual type, generally to complete by the operation of respective numbers according to number of chips, if the sensor with two chip blocks is encapsulated, complete by first, second two procedures, namely a workman first carries out a glue and die bond on a position of substrate, and then by own or hand to the next bit workman and carry out again a glue and die bond on another position of substrate, complete the chip of whole sensor and the packaging operation of substrate.Due to, all production scale in large quantity now, encapsulate with this manual type, in the handshaking of two procedures, need to material be transported to next process from a procedure by artificial or equipment toward contact, sometimes also can need first material to be collected operation, then also need material is proceeded apportioned effort after complete transporting, give the operation that the workman carries out next process.
Realize it being generally to complete packaging operation by many similar equipment by half manual type, these equipment are respectively completed the operation to the substrate with a slice chip package, are therefore that the quantity of these equipment need to be set according to the quantity of chip.Similarly that this mode is also to need by artificial or equipment, material to be transported to next process from a procedure in the handshaking of two procedures with manual type.
Top several modes of saying mainly exist following shortcoming:
At first, artificial mode has all dropped into a large amount of manpowers from the packaging operation to the transport operation etc., high to the manpower degree of dependence, and half artificial mode, although realized the machine operation of packaging operation, but it is not for transport operation etc. or need to drop into a certain amount of manpower, still low to the degree of dependence of manpower; What can see is: on the one hand, artificial or half artificial operating type, its production efficiency is also obviously not high, and workman's mood just certainly will all can have influence on its work, makes working (machining) efficiency unstable; On the other hand, in today that human cost day by day is expected to rise and the recruitment famine occurred, many enterprises are all doing one's utmost to compress number of workers, control the cost payout of enterprise or guarantee the normal production of enterprise, and this operating type obviously is difficult to satisfy the demand of enterprise;
Secondly, in above-mentioned mode, all to disconnect carrying out operation between each procedure, process lacks continuity, and the operation that separates between each procedure also can have influence on the uniformity of operation effectiveness, and each species diversity that occurs between finished product also can cause the control that is difficult to product yield further, has affected potentially the quality of finished product.
Therefore, in order to complete better the operation of multi-chip packaging of the fiber grating sensors, need a kind of equipment that can overcome above-mentioned shortcoming badly.
