Abstract
The invention discloses a quartz crystal resonator which comprises a resonator body and a lead wire. The lead wire is connected with the resonator body, the resonator body comprises a quartz crystal wafer, a film plating electrode, a base and a casing, the lead wire comprises a wide lead wire portion and a narrow lead wire portion which are connected together, the size of the horizontal wide edge of the wide lead wire portion is larger than the horizontal size of the narrow lead wire portion, and the wide lead wire portion is located at the position which is close to the resonator body. The invention further provides a reflow soldering method used by the quartz crystal resonator. By means of the reflow soldering method, the problem of reflow soldering of plug-in type quartz crystal resonators is solved, and production costs of electronic products can be reduced.
Description
Technical field
The utility model relates to the electronic devices and components field, relates in particular to a kind of quartz-crystal resonator.
Background technology
In recent years, great variety has taken place in the SMT technology, as the use of the change of production standard, novel soldering paste, the appearance of different substrate materials and the innovation of the material of element own and design, all to reflow soldering process new requirement has been proposed, be exactly total more advanced thermaltransmission mode and control mode are adopted in one trend requirement, reach energy savings, uniform temperature, be fit to the welding requirements of double sided board and new device packaged type, and progressively realize the full substitution to wave-soldering.Along with the miniaturization of terminal electronic product, the continuous quickening of ultra-thinization process, various electronic components are also developing to miniaturization, SMD direction.At present each complete machine user to the demand of crystal element excessive to the SMD type by the DIP plug-in type, but because the surface-adhered type product exists production equipment, checkout equipment costliness, the material cost height, production cycle, long factor caused patch-type product price height, terminal use for the enough electronic products of installing space just exists puzzled: if all adopt SMD patch-type product, certainly will increase the cost of processed materials purchased; But adopt SMD SMD as fruit part, what another part adopted the DIP plug-in type can carry out wave-soldering and Reflow Soldering two procedures, very big to the double-clad board increase especially difficulty respectively again on production technology.Consideration for cost control, under the unrestricted situation in electronic product space, the electronic component that SMD patch-type and DIP plug-in type are arranged on the pcb board usually simultaneously, on production technology, both needed the Reflow Soldering welding, need the wave-soldering welding just can finish the connection of electronic component on the entire circuit plate again, need the twice welding sequence to finish, if all adopt surface mount elements, can increase material cost.
The utility model content
The utility model aims to provide a kind of quartz-crystal resonator, is used for addressing the above problem, and realizes the Reflow Soldering welding of plug-in type quartz-crystal resonator, lowers the production cost of electronic product.
For achieving the above object, the utility model is realized by the following technical solutions:
The disclosed quartz-crystal resonator of the utility model, comprise the resonator body, with the lead-in wire that the resonator body is connected, described resonator body comprises quartz wafer, coated electrode, pedestal, shell; Described lead-in wire comprises the wide leading part that links together, narrow leading part, and the horizontal broadside size of described wide leading part is greater than the lateral dimension of narrow leading part, and described wide leading part is positioned at the position near the resonator body.
Preferably, the horizontal broadside of described wide leading part is of a size of 1.0mm and following.
Preferably, the height of described wide leading part is 1.2mm and following.
Preferably, described wide leading part is flat, and its broadside can any angular orientation form.
The utility model is owing to there is the support of wide leading part, the element base plate can not contact with pcb board and tin cream when welding, so just can weld by the mode of Reflow Soldering together with other surface mount elements, reduced wave-soldering technology, purchase cost is lower than surface mount elements simultaneously, avoids solder joint bridge joint or short circuit phenomenon, can replace common patch-type product fully, and replacing wave-soldering by the Reflow Soldering mode fully, the success of this utility model will promote the development of electron trade, be significant.
The utility model can solve the Welding Problems that has SMD and two types of electronic components of DIP on the same pcb board simultaneously, can replace wave-soldering by Reflow Soldering fully, owing to reduced the wave-soldering welding sequence, has reduced production cost, has favorable economic benefit.
