Abstract
The utility model discloses a device for drying coolant in order to prevent bonding wires from getting stuck after being annealed. The device comprises a drying heating unit and a drying air-cooling unit, wherein the device is arranged between the coolant and a winding shaft on an online annealing furnace; the device is characterized in that the drying heating unit comprises a temperature controller, a temperature detection system, a heater and a heating controller; and the drying air-cooling unit is driven by a direct current ( DC ) motor to achieve the cooling effect. By adding the device to the coolant of the annealing furnace and heating and drying the coolant to volatilize the water in the coolant, the device of the utility model can solve the problem that the gold bonding wire is prone to get stuck after being annealed and improve the yield of products.
Description
Technical field
The utility model relates to a kind of drying and heating device, refers to a kind of cooling fluid drying unit that prevents bonding wire annealing back haircuts especially.
Background technology
Along with development extensive, super large-scale integration, more and more higher to the requirement of packaged material, also require high-performance when reducing cost.Semiconducter device is for reducing the high cost as the fine spun gold that connects lead-in wire usefulness, the para-linkage Herba Anoectochili roxburghii directly requires more and more thinner, and at present, ultra-fine bonding gold wire has reached below 17 microns, the spun gold miniaturization not only can reduce required spun gold expense, and is applicable to high density packing.Yet the requirement of this ultra micro refinement is also to every performance index of spun gold, few fracture of wire and unwrapping wire is smooth and easy, haircuts has not proposed a new challenge.
In existing bonding gold wire production process, need be heated 300-450 ℃ and anneal, generally adopt the continuous annealing furnace annealing, comprise take-up, actinobacillus device and be in process furnace between the two devices.Bonding gold wire directly is wound in the take-up axle in annealed stove heating back by cooling fluid, cooling fluid is that organism and water are formulated by a certain percentage, this show spun gold surface through cooling fluid can have large quantity of moisture and cause on take-up axle upper strata around the time can produce adhesion between silk and the silk, thereby influence the production of next process, unwrapping wire had some setbacks and causes broken string frequent when the client used, reduced the product lumber recovery, and haircuts can cause the single shaft winding length to reduce, production efficiency descends, the silk of producing same rice number can increase the usage quantity of axle, has improved production cost.
The utility model content
In view of this, the utility model is improved above-mentioned shortcoming, has added a cover cooling fluid drying unit on spun gold is produced annealing furnace, makes integrated the finishing of annealing, cooling, oven dry, take-up of spun gold, and this device is implemented simple and easy handling.
Main purpose of the present utility model is to solve the adhesion phenomenon that bonding gold wire annealing back produces, and improves the product lumber recovery.
Another purpose of the present utility model is to strengthen the single shaft winding length, saves production cost when improving operating efficiency.
The utility model is achieved in that bonding wire after annealed stove 1 is regulated mechanical property, enters into and carries out top coat and cooling in the cooling fluid 2, after this drying unit oven dry, is wound on the take-up axle 3.A kind of bonding wire annealing back that prevents produces the drying unit of haircuts, comprise oven dry heating unit and the air-cooled unit two parts of oven dry, the temperature regulator of heating unit is converted into electrical signal control heating controller with artificial design temperature, the output rating that heating controller is regulated heating unit with the electrical signal that temperature regulator sent through amplification, the heating take-off equipment is according to the regulating and controlling output rating of heating controller.The temperature detection feedback system feeds back to temperature regulator with heating unit current actual temperature signal through detecting, putting in order.Temperature regulator is feeding back the signal that according to the temperature detection feedback system, carry out self-control output electrical signal control heating controller, and Heating temperature can arbitrarily be adjusted between 0-300 ℃, and can open or close heating according to actual needs.Air-cooled unit is that air-cooled it is loose of a large amount of heat energy utilizations that well heater produces removed, and makes cooling fluid dehydration rapidly after forming a lubricant film on the bonding gold wire, and blower fan is driven by direct-current machine and reaches cooling performance.
Useful technique effect of the present utility model is: utilize in cooling fluid and take-up between centers to add drying and heating device, reduce layer around the time spun gold surface water content, and utilize cooling fluid on bonding gold wire, to form a lubricant film, solved bonding gold wire and produced adhesion phenomenon and the not long technical problem of single shaft coiling rice number on the same take-up axle through being wrapped in after the continuous online annealing, reduced and produced the quantity of using axle, when having improved product lumber recovery and production operation efficiency, reduced production cost.
