Abstract

The present invention discloses a kind of quartz-crystal resonator, the lead-in wire comprise resonator body, being connected with resonator body, and resonator body comprises quartz wafer, coated electrode, pedestal, shell; Lead-in wire comprises the wide leading part linked together, narrow leading part, and the horizontal broadside size of wide leading part is greater than the lateral dimension of narrow leading part, and wide leading part is positioned at the position near resonator body; The invention also discloses the method that this quartz-crystal resonator adopts reflow soldering.The invention solves a reflow soldering difficult problem for plug-in type quartz-crystal resonator, the production cost reducing electronic product can be lowered.

Description

A kind of quartz-crystal resonator and reflow soldering method thereof
Technical field
The present invention relates to electronic devices and components field, particularly relate to a kind of quartz-crystal resonator and reflow soldering method thereof.
Background technology
In recent years, SMT technology there occurs great variety, as the innovation of the change of production standard, the use of novel soldering paste, the appearance of different substrate materials and the material and design of element own, all propose new requirement to reflow soldering process, be exactly total the trend requirement of adopts more advanced thermaltransmission mode and control mode, reach energy savings, uniform temperature, be applicable to the welding requirements of double sided board and new device packaged type, and progressively realize the comprehensive replacement to wave-soldering.Along with the miniaturization of terminal electronic product, the continuous quickening of ultrathin process, various electronic component is also to miniaturized, SMD future development.Current each complete machine user to the demand of crystal element excessive to SMD type by DIP plug-in type, but because surface-adhered type product exists production equipment, checkout equipment costliness, material cost is high, the production cycle factor of length causes patch-type product price high, just there is puzzlement in the terminal use for the enough electronic product of installing space: if all adopt SMD patch-type product, certainly will increase the cost of processed materials purchased; But as fruit part adopts SMD SMD, what another part adopted DIP plug-in type can carry out wave-soldering and Reflow Soldering two procedures respectively again, difficulty very large to double-clad board increase especially in production technology.For the consideration of cost control, in the unrestricted situation in electronic product space, pcb board there is usually simultaneously the electronic component of SMD patch-type and DIP plug-in type, production technology both needed Reflow Soldering weld, need again Wave crest Welding just can complete the connection of whole electronic element on circuit board, need twice welding sequence to complete, if all adopt surface mount elements, can material cost be increased.
Summary of the invention
The present invention aims to provide a kind of quartz-crystal resonator and welding method thereof, for solving the problem, realizing the Reflow Soldering welding of plug-in type quartz-crystal resonator, lowering the production cost of electronic product.
For achieving the above object, the present invention realizes by the following technical solutions:
Quartz-crystal resonator disclosed by the invention, the lead-in wire comprise resonator body, being connected with resonator body, described resonator body comprises quartz wafer, coated electrode, pedestal, shell; Described lead-in wire comprises the wide leading part linked 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 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 be formed.
The invention also discloses the reflow soldering method of this quartz-crystal resonator, comprise the following steps:
Step 1, the pcb board that need weld quartz-crystal resonator provided by the invention coats tin cream;
Step 2, inserts lead-in wire on pcb board in corresponding aperture, until the bottom of wide leading part is pressed on this pcb board;
Step 3, sends above-mentioned pcb board into reflow soldering equipment, adopts the technique identical with welding SMD element to weld.
Owing to there being the support of wide leading part, element base plate can not contact with pcb board and tin cream, so just can be welded by the mode of Reflow Soldering together with other surface mount elements, decrease solder wave process, purchase cost is lower than surface mount elements simultaneously, avoids Solder or short circuit phenomenon, common patch-type product can be replaced completely, and replacing wave-soldering by Reflow Soldering mode completely, the success of this invention, by promoting the development of electron trade, is significant.
The present invention can solve the Welding Problems same pcb board with SMD and DIP two type electronic component, can replace wave-soldering completely, owing to decreasing Wave crest Welding operation, reduce production cost, have good economic benefit by Reflow Soldering.
