The flying needle tester does not depend on the pin pattern mounted on the fixture or bracket.Based on this system, two or more probes are mounted on tiny, free-moving heads in the xy plane, and the test points are directly controlled by CADI Gerber data.The dual probes can move within 4 mil of each other.The probes can move automaticaly, and there is no real limit to how close they can get to each other.The tester with two movable arms is based on capacitance measurements.The circuit board is placed tightly on an insulating layer on a metal plate that ACTS as another metal plate for the capacitor.If there is a short circuit between the lines, the capacitance will be larger than at a certain point.If there is a break, the capacitance will be smaller.

Test celeritate est momenti criterion pro eligens a tester.while et acus lectum testum potest accurate probare milia test puncta ad tempus, in volans acus tesseris potest tantum probare duo vel quattuor test puncta ad a TEPREFACTUM SIGNUM SIGNIPITIA PROCUS PUNCTI PRAETEREXO PRAESTRICIUS PRAETEREMUMINITIO PRAETEREMUMINITIO QUADLE.IGUS PRAETEREMA PRAETEREMA PRAETEREMUMINITIONE AT PRAESTRICTUM PRAESTRICTUM PUNCTI PRANCEPS PRAETEREUS PRAETEREMUMINITIO PRAETEREMUMINITIONE PRAETEREMENTUM puncta in tesle.In non solum test cum a volans acusque tetle exigit, cum a volans acus, qui est a volans et ad perficiendum est in eodem tempore. Shirley (MCMXCI) explicavit quod hoc modo est bonum choice pro fabrica complexu circuitu tabulas inferioribus cedit, etiam si manufacturers de summus volumine typis Circuit tabulas ad movens volantem pin Test Technique.

Nudum laminam temptationis, ibi dedicated test instrumenta (Lea, MCMXC) .A magis sumptus-effective accessus esset ad universum instrumentum, quamvis initio, quam ad boards et in initio, cum Pad erit maiori, quam adeoque 1.3mm.

For the Imm grid, the test pad is designed to be greater than 0.7mm.If the grid is small, the test pin is small, brittle, and prone to damage.Therefore, it is best to use grids larger than 2.5mm.Crum (1994b) stated that the combination of universal tester (standard grid tester) and flying needle tester can make the detection of high density circuit board accurate and economical.Another approach Ille insinuat est ut a PROLIXUS Flexilis tester, quod potest esse ad deprehendere puncta quod deviare de Grid.However, diversis iuga pads tractata cum calidum aer adtritio erit impedire nexum de test puncta.
Sequenti tres gradus deprehenduntur plerumque ferri:
I) nudus laminam deprehendatur;
II) online deprehensio;
III) Eget deprehendatur.
Generalis type tester potest esse ad deprehendere quaedam style et genus circuitus tabula tum pro speciali applications.
Commune metallum coatings sunt:
Aes
Tin

Et crassitudo est plerumque inter V et XV cm
Plumbum-stannum stagnum (vel stagni-aeris stilino)
Hoc est, solidatur, plerumque V ad XXV m crassitudine, cum stagni contentus de LXIII%

Aurum: plerumque non solum patella in interface

Silver plerumque tantum patella interface, totum etiam totum argentum
