Description
Technical field
The present invention relates to technical field of integrated circuits more particularly to a kind of debugging connection fixtures.
Background technology
Electronic product leak analysis needs to use UART (Universal Asynchronous Receiver/
Transmitter universal asynchronous receiving-transmitting transmitter interfaces, abbreviation UART), I2C or JTAG (Joint Test Action Group
Joint test working group, abbreviation JTAG), it needs to weld debugging interface stand in mainboard or increases debugging interface jig.
According to welding debugging interface stand, it is assumed that need to increase the connection stand of a 4PIN2.0 when volume production, tire out
The cost that product needs is higher.Current debugging interface stand mostly uses plug-in mode, because plug-in mode stand is in debugging
Plug debugging line is less likely to be damaged the copper sheet on printed circuit board, but plug-in unit stand, which accounts for area, than is unfavorable for printed circuit board greatly
Cabling can destroy the earth-return circuit of plug holder another side.Mainboard technique is all only to need Reflow Soldering, plug-in unit with surface mount elements at present
Technique needs to use wave-soldering mode, causes plank to need Reflow Soldering and the square mode of two kinds of wave-soldering, increases cost and patch
Time.
