Abstract
The utility model relates to a terminal stock belt structure, wherein, a stock belt body which is connected to a terminal is provided with guide holes and stock escapement holes, and isolation holes are punched on the thin part of the connection part of the terminal and the stock belt body. The stock escapement holes can reduce the area of the surface of the stock belt, and thus, the quantity of gilded liquid coated on the stock belt body can be saved; when the gilded liquid is coated on the contact area of the terminal in a coating process, a siphonage phenomenon can be partially generated on the thin part, the isolation holes has the functions of extending and isolating siphonage passages of the gilded liquid, and thus, gilded loss which is caused by a case that gilded feed stocks are plated on the stock belt body is prevented.
Description
The relevant a kind of terminal material belt structure of the utility model refers in particular to a kind of terminal material belt structure of saving BGA (Ball Grid Array, ball grid array) the type junctor of consumption gold amount in the electroplating process.
Upgrading along with computer CPU, computer inside is increased sharply to five, 600 in order to the numbers of terminals of the socket type connector of accepting CPU, and be anti-plug intensity and the conductive effect that strengthens terminal, generally all need its contact jaw is carried out craft of gilding, gold is a noble metal, so a small amount of saving on every butt can reduce production costs significantly.Yet, the terminal material belt of existing BGA junctor as shown in Figure 1, existing terminal 1 and strip main body 2 thereof are connected by a thin portion 3, wherein make a large amount of bullports 21 in strip main body 2 upper punches, terminal 1 has in order to welding zone 12 that is welded in printed circuit board (PCB) (not shown) and the zone of action 11 in order to connect mutually with the CPU pin, and zone of action 11 is positioned at the top of terminal 1 and is connected in strip main body 2 by thin portion 3.In the brush plating process, behind brush gold plating liquid on the zone of action 11 at terminal 1, it is gold-plated that the surface of zone of action 11 can form one deck.
Though aforesaid method can conveniently be finished the gold-plated process of zone of action 11, yet in the brush plating process, produce siphonage at tiny thin portion 3 places easily, make excessive in a large number extremely thin portion 3 of gold plating liquid and strip main body 2 and form gold plate on the strip surface, thereby cause the waste of golden raw material, also make production cost too high and be unfavorable for promoting enterprise competitiveness.
The utility model purpose is to provide a kind of terminal material belt structure of saving the consumption gold amount of electroplating process and having the BGA junctor of good electric property.
The purpose of this utility model is achieved in that on the strip main body of terminal material belt structure and offers a large amount of bullports, the one side has terminal, be connected thin portion and be provided with one between terminal and strip, it is characterized in that: also punching out goes out a large amount of slug holes between thin portion of connection and bullport, and makes the obstruct hole in above-mentioned thin portion upper punch.Slug hole can reduce the area of strip body surfaces, thereby can reduce the gold plating liquid that strip main part branch attaches, in the brush plating processing procedure when the zone of action of terminal brush gold plating liquid, can produce the part siphonage in above-mentioned thin portion, and described obstruct Kong Zeke prolongs and intercept gold plating liquid siphon path, and then prevents that unnecessary golden raw material is plating to and cause the loss of consumption gold on the strip main part.
Because adopt such scheme, the utility model terminal material belt structure can be saved spent golden raw material in electroplating process, thereby can reduce production costs.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 is the plan view of existing terminal and strip main body thereof.
Fig. 2 is the plan view of the utility model terminal and strip main body thereof.
See also shown in Figure 2, the strip main body 5 that the utility model terminal material belt structure (not label) comprises terminal 4, be connected with terminal 4 and in order to the thin portion 6 of splicing ear 4 and strip main body 5.Wherein terminal 4 has weld part 41, contact part 42 and is arranged between the two connection section 43, weld part 41 is used for being welded in printed circuit board (PCB) (not shown), connection section 43 is provided with interference part 431, to interfere the location with the pilot hole inwall (not shown) of socket type connector, contact part 42 is arranged at the top of terminal 4, and it is connected with strip main body 5 by thin portion 6.
Offer the obstruct hole 61 that is provided with along thin portion lengthwise direction in the thin portion 6, in (the adopting brush-plating technique usually) process of plating, on contact part 42, brush gold plating liquid, tiny thin portion 6 places easily produce siphonage, when the gold plating liquid overflow of 42 brush platings of contact part during to thin portion 6, the effect that this obstruct hole 61 has obstruct and prolongs the siphon path, thus stop the further siphon of gold plating liquid to strip main body 5.
Please continue to consult Fig. 2, on strip main body 5, offer a large amount of bullports 51, location and traction when being convenient to terminal 4 manufacturings, the bottom offers perpendicular to the slug hole 52 that intercepts hole 61 length directions near 61 places, above-mentioned obstruct hole, when gold plating liquid from thin portion 6 further overflows during to strip main body 5, this slug hole 52 is the effect of tool obstruct also, and owing to be provided with a large amount of slug holes 52, make the surface area of strip main body 5 greatly reduce, cause the waste of consumption gold thereby avoid strip main body 5 to adhere to too much gold plating liquid.By said structure, can prevent the further loss of gold plating liquid, reach the purpose of saving golden raw material.
Claims (4)
1. terminal material belt structure, comprise terminal, strip main body and be connected in thin portion between the two, wherein terminal has contact part that is arranged at an end and the weld part that is arranged at the other end, link to each other by a junction therebetween, it is characterized in that: be arranged on the strip main body of terminal one side and offer bullport, and the strip between bullport and the terminal is provided with the hole.
2. terminal material belt structure as claimed in claim 1 is characterized in that: the hole of offering on the strip between above-mentioned bullport and the terminal is a slug hole.
3. terminal material belt structure as claimed in claim 2 is characterized in that: offer in the thin portion between strip main body and the terminal and intercept the hole.
4. terminal material belt structure as claimed in claim 3 is characterized in that: the length direction and the slug hole in above-mentioned obstruct hole are vertical relation.
