Abstract
A kind of four directions fillet pass plants tin steel-screen, which is characterized in that the plant tin steel-screen, including substrate, the netted hole that is opened on substrate, which is cubic fillet hole, which includes four right-angle sides, and fillet is pressed from both sides between every two adjacent right-angle sides.Four straight flanges of netted hole, which prevent from planting tin process, to be subjected to displacement, and tin is planted in more preferable positioning, makes plant tin precision higher, more accurate；The effect of four fillets is mainly heated in solder implantation process by temperature, makes tin ball more mellow and fuller and full, convenient for planting the disengaging process of tin ball, prevents falling off for tin ball in separation process, is reached and is preferably planted tin effect, raising working efficiency.
Description
【Technical field】
The utility model is related to chip package field more particularly to a kind of mount and reprocess for SMT/BGA fields
Technical field.
【Background technology】
Plant tin process is carried out on chip to need to use plant tin steel-screen, steel mesh is located on chip, being equipped on steel mesh
Tin hole is planted, tin ball is placed on each plant tin hole, makes the fusing of tin ball be fixed on chip by heating or other welding techniques
On, steel mesh is removed after cooling, to complete to plant tin process.
The existing netted hole for planting tin steel-screen is all rectangular or round, during planting tin plant pearl, is easy to happen position
Offset is set, causes plant tin ball irregular and not full, causes plant tin ineffective, it is existing to be also susceptible to plant tin ball card netted hole
As there is pearl phenomenon, causing to plant tin failure.
【Invention content】
The utility model proposes a kind of cubic fillet pass plant tin steel-screen in view of the above problems, and tin is planted in preferably positioning,
So that planting tin precision higher, more acurrate, avoids the occurrence of and block mesh, fall pearl phenomenon.
Described in the utility model to be related to being that cubic fillet pass plants tin steel-screen, which plants tin steel-screen, including
Substrate, the netted hole being opened on substrate, the netted hole are cubic fillet hole, which includes four right-angle sides, every two
Fillet is pressed from both sides between adjacent right-angle side.
The netted hole has several, is evenly distributed on substrate.
There is white space among netted hole on substrate, which constitutes a square pattern.
It is all provided on rectangular each angle of white space there are one netted hole is positioned, there are four positioning for entire white space tool
Netted hole.
The positioning netted hole is also cubic fillet hole.
Cubic circular hole involved by the utility model plants tin steel-screen, and four straight flanges of netted hole of use prevent from planting tin process
It is subjected to displacement, tin is planted in more preferable positioning, makes plant tin precision higher, more accurate；The effect of four fillets is mainly in solder implantation process
In heated by temperature, make tin ball more mellow and fuller and full, convenient for plant tin ball disengaging process, prevent tin ball in separation process
It falls off, reaches and preferably plant tin effect, improve working efficiency.
【Description of the drawings】
Fig. 1 is the structural schematic diagram that the utility model four directions circular hole plants tin steel-screen；
Fig. 2 is the netted hole enlarged drawing on the circular hole plant tin steel-screen of the utility model four directions；
Wherein：10, substrate；20, netted hole；21, right-angle side；22, fillet；30, white space；31, netted hole is positioned.
【Specific implementation mode】
Tin steel-screen is planted below in conjunction with accompanying drawings and embodiments to the utility model four directions circular hole to be described in detail.
Examples of the embodiments are shown in the accompanying drawings, and in which the same or similar labels are throughly indicated identical or classes
As element or element with the same or similar functions.The embodiments described below with reference to the accompanying drawings are exemplary, only
For explaining the utility model, and should not be understood as limiting the present invention.
In the description of the present invention, it should be understood that term "center", "upper", "lower", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indicates or imply and is signified
Device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to this practicality
Novel limitation.
Attached drawing 1 is please referred to, cubic fillet pass is shown and plants tin steel-screen, which plants tin steel-screen, packet
Substrate 10, the netted hole being opened on substrate 20 are included, which is cubic fillet hole, which includes four right angles
Side 21 presss from both sides fillet 22 between every two adjacent right-angle sides.
The netted hole 20 has several, is uniformly distributed on the substrate 10.
There is white space 30 among netted hole 20 on the substrate 10, which constitutes a square pattern.
It is all provided on the rectangular angle of white space 30 there are one netted hole 31 is positioned, there are four fixed for entire square pattern tool
Position netted hole 31.
The positioning netted hole 31 is also cubic fillet hole.
Four straight flanges of netted hole, which prevent from planting tin process, to be subjected to displacement, and tin is planted in more preferable positioning, makes plant tin precision higher, more
It is accurate；The effect of four fillets is mainly heated in solder implantation process by temperature, is made tin ball more mellow and fuller and full, is convenient for
The disengaging process for planting tin ball prevents falling off for tin ball in separation process, reaches and preferably plants tin effect, improves working efficiency.
The above is only the utility model preferred embodiment, is not made in any form to the utility model
Limitation, although the utility model is disclosed above with preferred embodiment, is not limited to the utility model, any to be familiar with sheet
Technical professional is not departing within the scope of technical solutions of the utility model, is made when using the technology contents of the disclosure above
A little change or the equivalent embodiment for being modified to equivalent variations, as long as being without departing from the content of the technical scheme of the utility model, foundation
The utility model technology refers to belonging to this practicality to any simple modification, equivalent change and modification made by above example
In the range of new technique scheme.
