Embodiment
The invention provides a kind of welding method and a kind of data card of HDMI interface, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
The present invention be directed to the data card type that has the HDMI interface, namely directly be welded with the HDMI interface on the pcb board of this data card.
The welding method of a kind of HDMI interface as shown in Figure 1, described HDMI joint weld wherein, may further comprise the steps on PCB:
S100: print solder paste in the pad of HDMI interface to be welded on PCB, cross reflow ovens and carry out the heating first time, solidify tin cream.Process at welded H DMI on the PCB of the present invention is at the SMT(surface mounting technology) finish in the paster technique process, wherein, use seal tin machine that the pad that PCB goes up HDMI interface to be welded is carried out going up in advance tin, this process is to need the pad print solder paste process of surface mount elements to carry out simultaneously with other.Therefore, can utilize the technology of original SMT and the welding that equipment can be finished the HDMI interface, realize automated production.
When crossing reflow ovens (four stove districts) heating in the described steps A, maximum temperature is 245 ℃.The length of the tin cream that prints in the pad of HDMI interface to be welded on PCB is the 65-75% of described pad length, and tin cream is oversize, connects the tin short circuit because how tin causes easily, and if tin cream is too short, pin can be because tin rosin joint or sealing-off very little and easily.Guaranteed that in this scope tin short circuit and rosin joint sealing-off phenomenon can not appear in tin cream, have guaranteed the pin welding reliability.In the most preferred embodiment, the length of print solder paste is 75% of pad length.
Glass putty content is 88%(SAC305 in the printed tin cream in addition).Can guarantee like this that tin cream has suitable viscosity, guarantee that the pin of HDMI interface in the following step and the welding of pad have best printing effect, the best curing temperature of tin cream is 220 ℃.
S200: the pin of HDMI interface is inserted on the described pad, and brushes scaling powder at described pin.
Other element tin creams of tin cream and PCB are after reflow ovens is heating and curing on the pad of HDMI interface to be welded, and the pin 220 of as shown in Figure 3 HDMI interface 200 is inserted on the pad that solidifies tin cream, insert good back and form as shown in Figure 2 effect.For guaranteeing welding effect, also to brush scaling powder or weld-aiding cream at pin 220, described scaling powder is the aqua shape, model is Sang Laisi SR09A-1, the consumption of scaling powder can not be too many, institute's consumption accounts for 11 ~ 12% of tin cream consumption, generally uses 0.1ml to get final product, but the automation of brushing process is carried out also using small brushes to dip in and got the scaling powder brushing.
Since after carry out heating process for the second time through reflow ovens and can cause insulation plastic layer 210 temperature distortions in the HDMI interface 200, so be plugged with the protective sleeve 300 that is used for preventing insulation plastic layer 210 distortion in the HDMI interface as shown in Figure 4 in the spliced eye that the insulation plastic layer of HDMI interface 200 forms.Described protective sleeve 300 comprises the inserted terminal 310 that inserts in the HDMI interface and is positioned at the outer holding end 320 of HDMI interface that the spliced eye shape that the shape of described inserted terminal 310 and described insulation plastic layer 210 form is adaptive.Effect after the grafting as shown in Figure 5, the insulation plastic layer that protective sleeve 300 can guarantee the HDMI interface projection, indent phenomenon do not occur because being heated, and has guaranteed the production quality of HDMI interface.
S300: described PCB is carried out second time heating by reflow ovens, the pin of described HDMI interface is welded on the described PCB.
After being plugged into protective sleeve in the HDMI interface, and the HDMI interface is inserted on the PCB respective pad, enter before reflow ovens is carried out heating for the second time design sketch as shown in Figure 2, then it is carried out the second time and heats, make the HDMI joint weld to PCB.The furnace temperature curve of this heating process as shown in Figure 6, as can be seen from the figure the highest furnace temperature is 245 ℃.This process also is the process of other surface mount elements welding, so this furnace temperature curve is the same with product furnace temperature curve.Therefore only need to use the SMT technology of routine and the welding that equipment can be finished the HDMI interface.And need not to arrange separately operation welded H DMI interface, also need not to change technological parameter, guaranteed production efficiency.
Adopt reflow ovens to be heating and curing to have guaranteed stable heating, realize automation process simultaneously, guaranteed the homogeneity of product quality, avoid the instability of the product quality that the deviation of artificial heating causes.
A kind of data card comprises HDMI interface and PCB, and described HDMI interface adopts the welding method of aforesaid HDMI interface to be welded on the PCB.
The invention provides a kind of welding method and a kind of data card of HDMI interface, by carrying out the SMT welding on the corresponding pad that the HDMI interface directly is plugged into PCB, the low problem of poor efficiency, yields of original manual welding or the expensive problem of using infrared/laser-beam welding machine to bring have been avoided, make the welding of the HDMI interface on the PCB can use original SMT technology and equipment, realize the automation welding process on the basis that the assurance cost does not increase, improved efficient and yield of products.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection range of claims of the present invention.
