Abstract
The utility model relates to a preheating device of electronic components mold pressing procedure, the electric heater who includes base, pillar, preheats the platform and be connected with the power, the bottom of pillar and base fixed connection, the top of pillar with preheat a fixed connection, electric heater establishes on the base. The utility model is not only simple in structure, and can preheat the work piece, because of the stress damage of high temperature to the lead frame when reducing the mould pressing.
Description
Technical field
The utility model relates to a kind of preheating device, is specifically related to a kind of preheating device of electronic devices and components mold pressing procedure.
Background technology
Existing electronic devices and components are in preparation process, mold pressing procedure will be carried out after carrying out welding sequence, described mold pressing procedure refers to the chip of electronic devices and components and is coated in insulating cement shell with the paster Ji Dao of the lead frame of chips welding, the rear workpiece being about to weld will be placed in mold pressing frock in advance, then baking oven drying is put into, in described baking oven, the temperature of drying controls within the scope of 145 ~ 155 DEG C, because workpiece is be in normal temperature state before mold pressing, like this, when workpiece directly enters mold pressing procedure, just be easy to because the high temperature in baking oven causes stress damage to lead frame, directly will have influence on the reliability of final products.
Summary of the invention
The purpose of this utility model is: not only structure is simple to provide one, and can carry out preheating to workpiece, because high temperature is to the preheating device of the electronic devices and components mold pressing procedure of the stress damage of lead frame during minimizing mold pressing, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is: a kind of preheating device of electronic devices and components mold pressing procedure, its innovative point is: the electric heater comprising base, pillar, pre-heating station and be connected with power supply, the bottom of described pillar is fixedly connected with base, the top of pillar is fixedly connected with pre-heating station, and described electric heater is located on base.
In technique scheme, described electric heater has multiple, and base is provided with along its length four row's electric heaters, and often row's electric heater has two.
In technique scheme, the spacing between described pre-heating station and electric heater controls within the scope of 10cm ~ 20cm.
In technique scheme, pre-heating station is passed at the top of described pillar, and be fixedly connected with pre-heating station by clamp nut.
In technique scheme, described pillar has 4, and 4 pillars are arranged in four corners of base.
The good effect that the utility model has is: after adopting preheating device of the present utility model, the workpiece welded is placed on after in welding tooling and is placed on again on pre-heating station, then by electric heater, first preheating is carried out to workpiece, the preheat temperature of workpiece is made to reach about 80 DEG C, and then implement mold pressing procedure, like this, when effectively can slow down workpiece mold pressing, because of the stress damage that high temperature causes lead frame, improve the reliability of final products; Meanwhile, it is simple, easy to operate that the utility model also has structure, and practicality is high, achieves the purpose of this utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described, but is not limited thereto.
As shown in Figure 1, 2, 3, a kind of preheating device of electronic devices and components mold pressing procedure, the electric heater 4 comprising base 1, pillar 2, pre-heating station 3 and be connected with power supply, the bottom of described pillar 2 is fixedly connected with base 1, the top of pillar 2 is fixedly connected with pre-heating station 3, and described electric heater 4 is located on base 1.
As shown in Figure 2, in order to shorten the warm-up time of workpiece, improve the pre-heat efficiency, described electric heater 4 has multiple, and base 1 is provided with along its length four row's electric heaters 4, and often row's electric heater 4 has two.That is, multiple electric heater 4 is arranged on base 1 in the matrix form of 2*4.
As shown in Figure 1,3, in order to make the utility model structure more reasonable, the spacing between described pre-heating station 3 and electric heater 4 controls within the scope of 10cm ~ 20cm.
As shown in Figure 1,3, for the ease of equipped, pre-heating station 3 is passed at the top of described pillar 2, and be fixedly connected with pre-heating station 3 by clamp nut 5.
As shown in Figure 1, in order to improve the reasonability of the utility model structure further, pillar 2 described in the utility model has 4, and 4 pillars 2 are arranged in four corners of base 1.
When the utility model uses, switch on power, the workpiece welded wouldn't be taken out from welding tooling, be then placed on pre-heating station 3, implement the preheating to workpiece, treat that the preheat temperature of workpiece reaches about 80 DEG C, implement mold pressing procedure again, like this, effectively can slow down workpiece when mold pressing, because of the stress damage that high temperature causes lead frame, improve the reliability of final products; Meanwhile, also to have structure simple, easy to operate for the utility model.
The utility model pilot run shows, and its effect is well-content.
