Description

A kind of welding support of connector

Technical field

The utility model relates to welding technology field, especially a kind of welding of Type-C Lightning connector Bracket.

Background technique

Universal serial bus (English: Universal Serial Bus, abbreviation: USB) is connection computer system and outer A kind of serial bus standard of portion's equipment and a kind of technical specification of input/output interface are widely used in personal electricity The information communications product such as brain and mobile device, and extend to other correlations such as photographic goods, DTV (set-top box), game machine Field.Latest generation is USB 3.1, transmission speed 10Gbit/s, three-stage voltage 5V/12V/20V, maximum power supply 100W, Type-C is a kind of connecting interface of USB interface, be can be inserted into regardless of tow sides, the completely new Lightning Dock of apple Interface, Chinese can put it into the pluggable interface of " lightning " interface and tow sides.

Since TYPE-C and Lightning connector is double lateral plate, if directlying adopt existing welding method, Need Reflow Soldering twice again after the lateral plate of connector twice, it is meant that allow the scolding tin for having melted and having solidified to melt again, climb Tin.It has volatilized since the scaling powder in the tin cream that melted is heated, so welding and highly difficult, rosin joint of climbing Xi Douhui again Probability is big, and fusing point is coarse, can generate clutter when crossing high-frequency signal.For this purpose, Chinese invention patent CN107171158A is disclosed A kind of production method of USB TYPE-C mould group pastes electronic component by tow sides print solder paste and SMT process In PCB jigsaw specified location, the PCB jigsaw is then cut into several strip circuit boards, from two sides by connector Two rows of pins are clamped on the strip circuit board in the respective pad on each pcb board two sides, by the connector that is plugged with Strips lath is sent into reflow soldering furnace and is welded, and a Reflow Soldering is carried out；Due to only once Reflow Soldering the step of, no In the presence of allowing the scolding tin for having melted and having solidified to melt again, climbing tin, rosin joint probability is big, the coarse technical problem of fusing point.

But the above-mentioned prior art needs to be respectively adopted two fixtures and is positioned for two-face printing tin cream, and front and back exists Time difference is long, so that tin cream state is different, is easy to produce rosin joint in later period reflow process；And in Printing Paste In the process, it if positioning is unstable, is easy to influence Type-C so that print unevenness is even, while also will affect later period welding quality The service life of interface, and the above problem is the technical issues of the sector is not easy discovery.
