Abstract
The utility model discloses precision circuit plate weld to repair multiplexer, is related to circuit board technology field.Precision circuit plate weld repaiies multiplexer, including for connecting the sealing wire of broken position, the sealing wire is platypelloid type.The beneficial effects of the utility model are：It is simple in construction, increases the contact area with circuit board, reduces the thickness of welding wire, makes welding more firm, and flat welding wlding can more accurately reduce the point position that circuit board is lacked, and be molded standard, greatly improve operating efficiency.
Description
Technical field
Circuit board technology field is the utility model is related to, particularly precision circuit plate weld repaiies multiplexer.
Background technology
When circuit board usage time length or damage, broken string is easily caused.The generally use copper cash when breaking
Welded.But existing sealing wire cross section is generally circular, and its is a diameter of for the minimum sealing wire of existing diameter
0.2mm, especially when repairing bga chip with underlying circuit mainboard broken string, bga chip is caused to weld because sealing wire thickness is too high
It is bad with circuit main board localized contact (gap after bga chip installation between circuit board is 0.1-0.2mm) afterwards, using circle
Sealing wire easily causes bga chip and circuit main board contact area small, easily comes off.
Utility model content
To solve deficiency of the prior art, the utility model provides a kind of precision circuit plate weld and repaiies multiplexer, it
It is simple in construction, the thickness of welding wire is reduced, increases the contact area with circuit main board, makes welding more firm, it is flat
Shape sealing wire can more accurately reduce the point position that circuit board is lacked, and be molded standard, greatly improve operating efficiency.
The utility model to achieve the above object, is achieved through the following technical solutions：The reparation of precision circuit plate weld fills
Put, including for connecting the sealing wire of broken position, the sealing wire is platypelloid type.
The sealing wire thickness is 0.01-0.1mm.
The sealing wire thickness is 0.1-0.2mm.
The sealing wire is copper cash.
Prior art is contrasted, the beneficial effects of the utility model are：
1st, the utility model sealing wire is platypelloid type, reduce the thickness of welding wire, increases and is connect with circuit main board
Contacting surface is accumulated, and makes welding more firm, and pancake sealing wire can more accurately reduce the point position that circuit main board is lacked, shaping
Standard, greatly improve operating efficiency.
2nd, sealing wire thickness is 0.01-0.1mm, is conveniently used for the welding of bga chip, is contacted well after making welding.
3rd, it is 0.1-0.2mm to weld line width, meets circuit board voltage requirement.
4th, sealing wire is copper cash, and conductor wire is good, and solderability is good, does not generate heat, and oxygen-proof property is good, and can at utmost be dropped
Low sealing wire thickness.

In scope defined herein.
Precision circuit plate weld repaiies multiplexer, including for connecting the sealing wire 1 of broken position, the sealing wire 1 is
Platypelloid type, the contact area with circuit board is increased, reduce the thickness of welding wire, make welding more firm, flattened round
Welding wlding can more accurately reduce the point position that circuit board is lacked, and be molded standard, greatly improve operating efficiency.
As optimization, the thickness of sealing wire 1 is 0.01-0.1mm, is conveniently used for the welding of bga chip, is followed by welding
Touch good.
As optimization, the width of sealing wire 1 is 0.1-0.2mm, meets circuit board voltage requirement.
Further, the sealing wire 1 is copper cash, and conductor wire is good, and solderability is good, does not generate heat, and oxygen-proof property is good, and energy
It is enough at utmost to reduce sealing wire thickness.
