Embodiment
The invention provides a kind of welding method of HDMI and a kind of data card, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention be directed to the data card type with HDMI, be i.e. the pcb board of this data card is directly welded with HDMI.
The welding method of a kind of HDMI as shown in Figure 1, described HDMI is welded on PCB, wherein, comprises the following steps:
S100: on PCB HDMI to be welded pad in print solder paste, cross reflow ovens carry out first time heating, solidify tin cream.The process of welded H DMI on PCB of the present invention is at SMT(surface mounting technology) complete in paster technique process, wherein, use the pad of print tin machine to HDMI to be welded on PCB to carry out going up tin in advance, simultaneously this process needs the pad print solder paste process of surface mount elements to carry out.Therefore, the technology and equipment of original SMT can be utilized can to complete the welding of HDMI, realize automated production.
When in described steps A, reflow ovens (four stove districts) heats excessively, maximum temperature is 245 DEG C.On PCB HDMI to be welded pad in the length of tin cream of printing be the 65-75% of described length of bonding pad, tin cream is oversize, easily causes connect tin short circuit because tin is many, and if tin cream is too short, pin can due to tin very little and easily rosin joint or sealing-off.Within the scope of this, ensure that tin cream there will not be tin short circuit and rosin joint sealing-off phenomenon, ensure that the reliability that pin welds.In most preferred embodiment, the length of print solder paste is 75% of length of bonding pad.
In tin cream printed in addition, glass putty content is 88%(SAC305).Can ensure that tin cream has suitable viscosity like this, ensure that the pin of HDMI in following step has best printing effect with welding of pad, the best curing temperature of tin cream is 220 DEG C.
S200: the pin of HDMI is inserted on described pad, and scaling powder is brushed on described pin.
On the pad of HDMI to be welded, tin cream and other element tin creams of PCB are after reflow ovens is heating and curing, and are inserted into by the pin 220 of HDMI 200 as shown in Figure 3 and solidify on the pad of tin cream, be plugged rear formation effect as shown in Figure 2.For ensureing welding effect, also to brush scaling powder or weld-aiding cream on pin 220, described scaling powder is aqua shape, model is Sang Laisi SR09A-1, the consumption of scaling powder can not be too many, amount used accounts for 11 ~ 12% of tin cream consumption, and general use 0.1ml, painting process can automation carry out also using small brushes to dip scaling powder brushing.
Due to carrying out second time heating process through reflow ovens and can cause insulated plastic glue-line 210 temperature distortion in HDMI 200 afterwards, thus be plugged with in the spliced eye that formed of the insulated plastic glue-line of HDMI 200 as shown in Figure 4 for preventing the protective sleeve 300 that in HDMI, insulated plastic glue-line 210 is out of shape.Described protective sleeve 300 comprises the inserted terminal 310 inserted in HDMI and the holding end 320 be positioned at outside HDMI, the spliced eye shape adaptation that the shape of described inserted terminal 310 and described insulated plastic glue-line 210 are formed.As shown in Figure 5, protective sleeve 300 can ensure that the insulated plastic glue-line of HDMI does not occur protruding, indent phenomenon because being heated to effect after grafting, ensure that the production quality of HDMI.
S300: described PCB is carried out second time heating by reflow ovens, the pin of described HDMI is welded on described PCB.
Be plugged into by protective sleeve after in HDMI, and HDMI be inserted in PCB respective pad, the design sketch before entering reflow ovens and carrying out second time heating as shown in Figure 2, is then carried out second time heating, HDMI is welded on PCB.As shown in Figure 6, as can be seen from the figure the highest furnace temperature is 245 DEG C to the oven temperature profile of this heating process.This process is also the process of other surface mount elements welding, and therefore this oven temperature profile is the same with product oven temperature profile.Therefore conventional SMT technology and equipment only need be used can to complete the welding of HDMI.And without the need to arranging separately operation welded H DMI interface, also without the need to changing technological parameter, ensure that production efficiency.
Adopt reflow ovens to be heating and curing and ensure that stable heating, realize automation process simultaneously, ensure that the homogeneity of product quality, the instability of the product quality avoiding the deviation of artificial heating to cause.
A kind of data card, comprise HDMI and PCB, described HDMI adopts the welding method of HDMI as above to be welded on PCB.
The invention provides a kind of welding method of HDMI and a kind of data card, SMT welding is carried out by the corresponding pad that HDMI is directly plugged into PCB, the high cost problem avoiding the poor efficiency of original manual welding, the low problem of yields or use infrared/laser-beam welding machine to bring, make the welding of the HDMI on PCB can use original SMT technology and equipment, the basis that wananty costs does not increase achieves automatic welding process, improves the yields of efficiency and product.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
