g6y g6y 8 precautions refer to the pcb relays catalog (x33) for information on general precautions. be sure to read these precautions before using the g6y relay . correct use airtightness when cleaning will last 1 minute at 70 c. complete cleaning within these conditions. micro strip line design ? it is advantageous to use the micro strip line in high-frequency transmission circuits because a low-loss transmission can be constructed with this method. by etching the dielectric base which has copper foil attached to both sides, the micro strip line will have a concentrated electric field between the lines and ground as shown in the following diagram. lines with impedance z ground pattern dielectric base (dielectric constant: e r ) ? the characteristic impedance of the lines z o is determined by the kind of base (dielectric constant), the base' s thickness, and the width of the lines, as expressed in the following equation. z o = 377 e r h w 1 + p w 2h 1 + in p w h w : line width e r : ef fective dielectric constant h: dielectric base thickness the copper foil thickness must be less than h. ? the following graph shows this relationship. micro strip impedance ( ) micro strip (w/h) w dielectric constant ( e r ) ? for example, when creating 50- w lines using a glass epoxy base with a thickness of 1.6 mm, the above graph will yield a w/h ratio of 1.7 for a dielectric constant of 4.8. since the base thickness is 1.6 mm, the width will be h 1.7 2.7 mm. the thickness of the copper foil ato is ignored in this design method, but it must be considered because large errors will occur in extreme cases such as a foil thickness of t w. furthermore, with the micro strip line design, the lines are too short for the g6y's intended frequency bandwidths, so we can ignore conductive losses and the line' s attenuation constant. ? the spacing of the strip lines and ground pattern should be comparable to the width of the strip lines. ? design the pattern with the shortest possible distances. excessive distances will adversely effect the high-frequency characteristics. ? spread the ground patterns as widely as possible so that potential dif ferences are unlikely to develop between the ground patterns. ? to avoid potential short-circuits, do not place the pattern' s leads near the point where the bottom of the relay attaches to the board. bending the micro strip line strip line with impedance z elbow clip the corners. when the lines must curve, an elbow can be used as shown in the diagram. a distance (d) between the lines of approxi - mately twice the line width is sufficient. 45 c
g6y g6y 9 examples of mounting designs since this example emphasizes reducing mounting costs, expen- sive mounting methods such as through-hole boards are not shown. if such methods are to be used, the characteristics must be studied carefully using the actual board configuration. using a double-sided paper epoxy board when double-sided paper epoxy boards are used, the dielectric constant will be approximately the same as that of glass epoxy boards ( e r =4.8). the width of the strip lines for a board with t=1.6 mm is 2.7 mm for 50 w and 1.3 mm for 75 w . for a board with t=1.0 mm the width is 1.7 mm for 50 w and 0.8 mm for 75 w . the following diagram shows an example pattern and the micro strip lines connected to the contact terminals are formed with pat - tern widths derived from the description above. the width between the micro strip lines and ground patterns are comparable to the mi - cro strip line width. there are jumpers between the upper and lower patterns at the points marked with xs in the diagram. improved characteristics can be obtained with more jumper locations. this method yields isola - tion characteristics of 65 db to 75 db at 500 mhz and 50 db at 900 mhz. at this point in the diagram the component side is the entire ground pattern side, but set aside approximately 2.0 mm 2.0 mm of the pattern for the contact terminals and coil terminals. strip line coil g6y using a single-sided board when a single-sided board is used, isolation characteristics of only 60 db to 70 db at 200 mhz can be obtained. when high frequency bands are to be used with a single-sided board, a metal plate can be placed between the base and relay and connected to the ground pattern. metal plate ground terminals metal plate printed circuit board pattern g6y with this method a metal plate is placed between the relay and base and connected to the pattern, as shown in the above diagram. the important point here is that 3 locations (the g6y' s ground termi - nal, the metal plate' s bent tabs (a), and the ground pattern) are sol - dered together at the same time. this method combines an inex- pensive single-sided board and inexpensive metal plate to yield the same characteristics as a double-sided board and good character - istics are obtained by grounding the g6y's ground terminal and metal plate in the same place. the metal plate must be attached to the base as described here. from this point, the methods used for strip line design are the same as for the double-sided board. mounting precautions be sure to securely attach the relay's base surface to the board during installation. the isolation characteristics will be af fected if the relay lifts of f the board. as shown in the enlarged illustration of the cross-section of part a, the g6y is designed to ensure better high-frequency characteristics if the stand-of f part of the g6y is in contact with the ground pattern of the pcb. therefore, the ground terminal and stand-of f part are elec - trically connected internally . should the through hole electrically connected to the contact termi - nal come in contact with the stand-of f part, the contact will be short- circuited with the ground, which may cause in an accident. as a preventive measure, keep at least a distance of 0.3 mm be- tween the stand-of f part and the through hole or land. for example, if the terminal hole on the pcb is 1 mm in diameter and the length b shown in the illustration is 1.4 mm, a distance of 0.3 mm or more will be provided between the through hole and stand-off part. pcb mounting cross-section of part a part a ground pattern stand-off part through hole ground terminal contact terminal ground terminal
