Abstract
The utility model provides a auxiliary component used for the tests of stamping elements or leads, which can be mounted and fixed on the stamping elements and circuit board and has a contact part comprising conductive materials and a control part connected electrically to the contact part. When the auxiliary component is mounted and fixed to the stamping elements or circuit plate, the contact part is in contact with and electrically connected to the solder pad of the stamping elements. In addition, the control part stands out of the stamping element. Therefore, tests or leads can be made by operating the control part to avoid all disadvantages brought from directly making a test and lead on the solder pad.
Description
Technical field
The utility model relates to a kind of auxiliary element that is used for Surface Mount component testing and lead-in wire, by this auxiliary element, can make operations such as the test of Surface Mount components and parts and lead-in wire become very easy.
Background technology
The development of current electronic product is maked rapid progress, and one of them trend is exactly that small product size is more and more littler, weight is more and more lighter.This just requires constantly to increase the density of components and parts on the limited PCB circuit board of electronic product, dwindle its size.The application of a large amount of littler Surface Mount components and parts also is in order to address this problem, but it has also brought aborning some the test difficulties in the particularly research and development process simultaneously.
Such as, when the Surface Mount components and parts on the electronic product are tested, the circuit parameter characteristic that often needs observation Surface Mount components and parts solder joint place, because the size of Surface Mount components and parts is little, the density height, and the size of equipment such as the probe of some testing equipments, probe is relatively large, also will avoid the pad of adjacent components and parts in test process, therefore is difficult to touch accurately and reliably the pad place of target element device.
In addition, need that sometimes the components and parts on the available circuit plate are done fly line and connect (i.e. lead-in wire), exactly original disjunct components and parts pad is coupled together with conductor.Same because the size of components and parts is little, the density height, the operator is difficult to will go between reliably successfully be welded on the components and parts pad, and sometimes not prison welding is solid, and breaking releasing has brought a lot of difficulties and unreliability to operation easily.
Moreover, directly on the components and parts pad, test or the welding meeting causes very big damage to circuit board.Such as because the pad of Surface Mount components and parts is very little, destroy this pad easily if directly do the multiple high temp welding thereon, serious meeting causes pad to come off, and causes the entire circuit blackboard newspaper useless.
In addition, from the operating efficiency angle, directly on very little Surface Mount components and parts pad, test and welding can be wasted a large amount of time and efforts.
From technological angle, directly on very little Surface Mount components and parts pad, test and weld, need certain technical merit.
And so far,, do not cause people's attention for above-mentioned all difficulties, and lack a kind of effective counter-measure, overcome these difficulties.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of test and lead-in wire, non-easy damaged components and parts that can more easily carry out the Surface Mount components and parts, can increase substantially operating efficiency, improve the auxiliary element of measuring accuracy and welding reliability, promptly is used for the test of Surface Mount components and parts and the auxiliary element of lead-in wire.
The test of Surface Mount components and parts or the auxiliary element of lead-in wire of being used for of the present utility model, have contact site that constitutes by electric conducting material and the operating portion that is connected with this contact site point, this auxiliary element can install and fix on Surface Mount components and parts or the circuit board, when installing and fixing this auxiliary element on Surface Mount components and parts or the circuit board, this contact site contacts with the pad of Surface Mount components and parts and is electrically connected, and this operating portion is outstanding and be convenient to operation to the superjacent air space of Surface Mount components and parts.
In addition, in above-mentioned auxiliary element, there is no particular limitation for the shape of operating portion, can be shape arbitrarily, and it gets final product so that the user operates on it so long as outstanding to the outside of Surface Mount components and parts.
In addition, this auxiliary element can install and fix on Surface Mount components and parts or the circuit board by variety of way, and specifically the mode of installing and fixing is not particularly limited, so long as after installing and fixing, contact site contacts with the pad of Surface Mount components and parts and gets final product.
As the execution mode that installs and fixes, multiple mode that can be as described below.
First kind of mode is to utilize snap device that this auxiliary element is installed and fixed mode on the Surface Mount components and parts.Among this mode, the snap device that can utilize the contact site itself by auxiliary element to constitute is clamped in example on these Surface Mount components and parts by its elastic force buckle; Also can utilize the snap device buckle of other setting to be clamped in example on the Surface Mount components and parts, in this case, contact site is formed on the snap device, and this operating portion can be formed directly on contact site, also can be formed on the snap device, with conductor contact site and operating portion be coupled together then; Two contact sites can also be set, between two contact sites, linking arm be set, by the contact site formation snap device at this linking arm and two ends.Above-mentioned buckle mode both can be in the end from the side buckle, also can be from the top buckle.
The second way is to utilize clamping device that this auxiliary element is fixed on the Surface Mount components and parts.
The third mode is to utilize bonding agent that this auxiliary element is adhesively fixed on these Surface Mount components and parts or the circuit board.Bonding agent can be conducting resinl, PUR etc.
Owing on circuit board, be equiped with various Surface Mount type components and parts to high-density; and the components and parts stock size of these Surface Mount types is very little; and spacing is also very little each other; when it being surveyed with probe etc.; touch through regular meeting on the pad of adjacent components and parts, in addition when wire bonds, if directly on pad, weld; sometimes also damage components and parts, perhaps not prison welding is solid.
For such Surface Mount components and parts being tested or being gone between, the inventor has invented auxiliary element as described above, because this auxiliary element can be installed and be fixed on Surface Mount components and parts or the circuit board, and have contact site that constitutes by electric conducting material and the operating portion that is electrically connected with this contact site, and when being installed to this auxiliary element on Surface Mount components and parts or the circuit board, contact site contacts and conducts with the pad of Surface Mount components and parts, and operating portion is outstanding to Surface Mount components and parts outer space, therefore, operator's operating space becomes broader, can utilize probe etc. to be in direct contact with tests on this operating portion, also lead-in wire directly can be welded on this operating portion, so just avoided directly the difficulty of probe contact on the pad of Surface Mount components and parts, but also can avoid when lead-in wire damaging components and parts or circuit board because directly on its pad, weld.
