The rocking body 94 includes a rocking body 941 that rocks, a rubber film (film-like elastic member) 942 that adheres to the surface of the rocking body 941 and rocks the rocking body 941, and a rubber film. And a support member 943 for supporting 942. In the present embodiment, the support member 943 is divided into two parts, and the rubber film 942 is sandwiched between the two parts, and the two parts are coupled by screws or the like, thereby supporting the rubber film 942. . The rubber film 942 supported by the support member 943 is disposed in a thin film shape in a direction orthogonal to the ascending / descending direction of the first hand unit 91.

The swing part main body 941 is fixed (for example, bonded) to the rubber film 942. In the present embodiment, the rubber film 942 is fixed to the upper surface of the swing part main body 941, but the present invention is not limited to this, and the rubber film 942 may penetrate the swing part main body 941. The surface of the swing part main body 941 may be covered. Further, the rubber film 942 may not be bonded to the swing part main body 941.
Further, the rocking body 94 is a locking portion 944 that regulates the rocking range of the rocking portion main body 941 so that the rocking portion main body 941 rocks more than necessary and excessive stress is not generated on the rubber film 942. have. The locking portion 944 is a member for locking the swinging portion main body 941 to the support member 943. Moreover, the latching | locking part 944 has a rocking | fluctuation control part.

As shown in FIG. 2, a space S <b> 1 is formed between the inner peripheral surface of the locking portion 944 and the outer peripheral surface of the swinging portion main body 941. The space S1 is a space for enabling the swinging part main body 941 to swing. The space S1 is designed so that the swinging part main body 941 swings by 0.5 degrees at the maximum. Thereby, excessive rocking can be prevented while securing a rocking range sufficient for the inspection of the rocking part main body 941.
A concave portion 941a extending in the vertical direction is formed on the outer peripheral surface of the swinging portion main body 941, and a convex portion 944a that engages with the concave portion 941a is formed on the inner peripheral surface of the locking portion 944. Thereby, the excessive rotation (turning) of the swing part main body 941 is prevented.

  In addition, a sealed space S3 is formed in the rocking body 94 by the rubber film 942 and the support member 943. An air hole 943a for air to enter and exit from the pressure adjusting means 99 is provided on the upper surface of the sealed space S3. When positive pressure is supplied from the pressure adjusting means 99 to the sealed space S3, the rubber film 942 bends downward so that the sealed space S3 expands. As a result, the swinging portion main body 941 is biased downward. The swinging part main body 941 urged downward is locked by the locking part 944.

  The first hand unit 91 is lowered in a state where the swinging portion main body 941 is locked to the locking portion 944 (a state where the sealed space S3 is pressurized), and a force larger than the pressure applied by the pressure adjusting means 99 Then, as shown in FIG. 4, the swinging portion main body 941 moves away from the locking portion 944 and follows the inclination of the testing individual socket 61 while swinging. Thereby, the IC device 100 can be uniformly pressed against the surface (probe pin) of the individual socket 61 for inspection.

  The pressure adjusting means 99 is not particularly limited as long as the pressure in the sealed space S3 can be adjusted. For example, the pressure adjusting means 99 is a pump, a flow path connecting the pump and the air hole 943a, and a position in the middle of the flow path. It can be set as the structure which has an electromagnetic valve to do. The electromagnetic valve can take a state where the pump and the air hole 943a communicate with each other, a state where the air hole 943a is closed, and a state where the air hole 943a is released to the atmosphere. Thereby, air can be supplied into sealed space S3 from a pump, or the air of sealed space S3 can be removed, and the pressure of sealed space S3 can be adjusted.

  A floating body 96 is arranged below the swinging part main body 941 via a floating means 95. The floating means 95 is composed of a plurality of steel balls 951 such as bearings. The steel ball 951 is disposed in a space S2 that allows the steel ball 951 to move in a plane (movement and rotation in the X and Y directions). The floating body 96 can move in the X and Y directions with respect to the swinging portion main body 941 or rotate around the Z axis (θ direction) by rolling the steel ball 951 in the space S2. Therefore, even when the IC device 100 held in the heat exchanging portion 912 is displaced in the X, Y, and θ directions with respect to the individual inspection socket 61, the individual IC socket 100 is more accurately detected. Can be pressed.

  Further, the swing mechanism 93 has a restoring means for returning the position of the floating body 96 moved relative to the swing portion main body 941 to the original position (natural state). The restoring means includes a leaf spring 97 fixed to the floating body 96. The swinging part main body 941 is in contact with the leaf spring 97 in four directions. For example, when the floating body 96 moves in the X direction, the leaf spring 97 in the Y direction bends in the X direction, and tries to return the floating body 96 to the original position by the stress of the leaf spring 97. Similarly, even if the floating body 96 moves in the Y direction or the θ direction, the floating body 96 tries to return to the original position by the stress of the leaf spring 97. Thereby, after the test of the IC device 100 is completed, the floating body 96 is restored to the original position, and the IC device 100 to be tested next is easily attracted. In the present embodiment, a plate spring is used as the restoring means, but a coil spring (compression spring, tension spring), an elastic body such as rubber, or the like may be used.

  The swing mechanism 93 has been described above. As shown in FIG. 2, a plate-like base 911 is fixed to the lower surface of the floating body 96 of such a swing mechanism 93. Further, a heat exchanging portion 912 is disposed on the lower side (−Z direction side) of the base 911, and the base 911 and the heat exchanging portion 912 are formed by four columnar members 917 disposed therebetween. It is connected. Further, a heat sink 914 is disposed between the base 911 and the heat exchanging portion 912 and in a gap formed by the member 917.

-Heat exchange section-
The heat exchange part 912 is a member that holds the IC device 100 and presses the IC device 100 against the individual socket 61 for inspection. The heat exchange unit 912 is also a member that performs heat exchange with the held IC device 100. As shown in FIG. 2, the heat exchange unit 912 includes two parts. Specifically, the heat exchange unit 912 includes a heater block 9121 located on the base 911 side and a contact pusher 9122 located on the lower side of the heater block 9121, and holds the IC device 100 on the lower surface of the contact pusher 9122. Press. The contact pusher 9122 is detachably fixed to the heater block 9121 by screwing, fitting or the like. Accordingly, a contact pusher 9122 suitable for the shape and size of the IC device 100 to be inspected can be appropriately selected, and the convenience of the apparatus is improved.

  Further, the lower surface of the contact pusher 9122 is a flat surface. Thereby, the IC device 100 can be pressed uniformly. Moreover, generation | occurrence | production of the clearance gap (heat insulation layer comprised with air) between the contact pusher 9122 and the IC device 100 can be suppressed. Therefore, the IC device 100 can be stably held by the heat exchange unit 912, and heat exchange (heat transfer) with the IC device 100 can be efficiently performed.

  The heater block 9121 and the contact pusher 9122 are each made of a material that is hard and has high thermal conductivity. Thereby, it becomes the heat exchange part 912 which can exhibit the function mentioned above reliably. The material that is hard and has high thermal conductivity is not particularly limited. For example, various metals such as iron, nickel, cobalt, gold, platinum, silver, copper, aluminum, magnesium, titanium, and tungsten, or of these metals Alloys or intermetallic compounds containing at least one kind, and oxides, nitrides, carbides, and the like of these metals can be given.

  As shown in FIG. 3, a suction hole 981 is formed on the lower surface of the contact pusher 9122. A suction means 983 and a gas injection means 984 for supplying a gas having a higher thermal conductivity than air are connected to the suction hole 981 via a switching valve 982, and the suction hole 981 is driven by the switching valve 982. And a state where the suction means 983 is connected and a state where the suction hole 981 and the gas injection means 984 are connected can be switched.

  The suction unit 983 includes a pump such as a vacuum pump, for example, and has a function of reducing the pressure in the suction hole 981. When the inside of the suction hole 981 is depressurized with the heat exchange unit 912 pressed against the upper surface of the IC device 100, the IC device 100 can be adsorbed and held. Accordingly, the IC device 100 can be transported from the shuttle jig 42 to the individual inspection socket 61 and the IC device 100 can be conveyed from the individual inspection socket 61 to the shuttle jig 43.

  The gas injection unit 984 has a function of supplying a predetermined gas from the opening of the suction hole 981 to the heat exchange unit 912 and the IC device 100. The gas to be supplied is a gas having a higher thermal conductivity than air (dry air). In particular, helium can be preferably used as such a gas. As described above, in order to efficiently perform heat exchange between the heat exchanging unit 912 and the IC device 100, the lower surface of the contact pusher 9122 is a flat surface and the gap with the IC device 100 is suppressed. In some cases, a minute gap may be formed between the heat exchanging portion 912 and the IC device 100 due to the above processing accuracy and the bending of the upper surface of the IC device 100. The air existing in the gap functions as a heat insulating layer, and the heat exchange efficiency between the contact pusher 9122 and the IC device 100 may be reduced. Therefore, by supplying gas between the contact pusher 9122 and the IC device 100 and filling the gap with the gas by the gas injection means 984, the above-described reduction in the efficiency of heat exchange can be suppressed.

  The gas supply by the gas injection means 984 is performed immediately before or simultaneously with the pressing of the IC device 100 to the inspection individual socket 61 by the first hand unit 91. Specifically, after the IC device 100 is transported to the inspection individual socket 61 by the first hand unit 91, the suction of the IC device 100 is once released. Then, the switching valve 982 is switched to connect the gas injection unit 984 to the suction hole 981, and helium is injected from the suction hole 981 between the heat exchange unit 912 and the IC device 100 by the gas injection unit 984. Then, while continuing to inject helium, the heat exchanging unit 912 is moved downward to press the IC device 100 to the individual inspection socket 61 with a predetermined inspection pressure. Thereby, the gap between the heat exchange unit 912 and the IC device 100 is filled with helium, and the first heat exchange between the heat exchange unit 912 and the IC device 100 can be performed efficiently. Therefore, the temperature control during the inspection of the IC device 100 can be performed with higher accuracy.

-Heater-
As shown in FIGS. 2 and 5, a heater 913 is embedded in the heater block 9121. When the heater 913 is driven, the heat of the heater 913 is transmitted to the IC device 100 via the heater block 9121 and the contact pusher 9122, and the IC device 100 is heated. As described above, by burying the heater 913 in the heater block 9121, the heat of the heater 913 can be efficiently transmitted to the IC device 100.

  The heater block 9121 is formed with two holes 9121a that extend in the Y direction and open on the side surface on the −Y direction side, and a rod-shaped heater 913 is inserted into each hole 9121a. Further, the two heaters 913 are arranged at both ends in the X direction avoiding the central portion of the heater block 9121. Although not shown, heat conduction grease is filled between the heater 913 and the inner peripheral surface of the hole 9121a so that the heat of the heater 913 is efficiently transmitted to the heater block 9121. Note that the arrangement of the heater 913 is not limited to this as long as the IC device 100 can be heated via the heat exchanging unit 912. For example, the heater 913 is arranged apart from the heater block 9121 and is heated by a heat pipe or the like. 9121 may be thermally connected.

  The heater 913 is not particularly limited as long as the IC device 100 can be heated. For example, various ceramic heaters such as an alumina heater, an aluminum nitride heater, a silicon nitride heater, a silicon carbide heater, and a boron nitride heater, and an electric wire such as a nichrome wire can be used. Various cartridge heaters using heat rays can be used. In addition, a Peltier element may be used although there is a difficulty in durability. Further, the heater 913 is not limited to a rod-shaped heater, and for example, a planar heater can be used.

-Temperature sensor-
As shown in FIGS. 2 and 5, a temperature sensor 916 is embedded in the heater block 9121. The temperature sensor 916 indirectly detects the temperature of the IC device 100 by detecting the temperature of the heater block 9121. As described above, since the heater block 9121 and the contact pusher 9122 are made of a material having high thermal conductivity, the temperature difference between the IC device 100 and the heater block 9121 is small, and the temperature sensor 916 embedded in the heater block 9121 is used. Also, the temperature of the IC device 100 can be detected sufficiently accurately.

  The heater block 9121 has a hole 9121b that extends in the Y direction and opens on the side surface on the −Y direction side, and a temperature sensor 916 is inserted into the hole 9121b. Further, although not shown, between the temperature sensor 916 and the inner peripheral surface of the hole 9121b is filled with heat conductive grease, so that the heat of the heater block 9121 is efficiently transmitted to the temperature sensor 916. ing.

  In particular, since the temperature sensor 916 is disposed so that the detection unit 9161 for detecting the temperature is located at the center of the heater block 9121 and overlaps the lower surface of the contact pusher 9122 and is located near the IC device 100. Can be detected more accurately. Further, the heater 913 and the temperature sensor 916 can be separated as much as possible by arranging the two heaters 913 in a rod shape and disposing them at both ends of the heater block 9121 in the X direction. Therefore, a decrease in the temperature detection system of the temperature sensor 916 due to the influence of heat from the heater 913 is suppressed.

  The temperature sensor 916 of the present embodiment is arranged to indirectly detect the temperature of the IC device 100, but the arrangement is not particularly limited as long as the temperature of the IC device 100 can be detected. For example, the temperature of the IC device 100 may be directly detected. Specifically, the temperature sensor 916 may be disposed so as to be exposed on the lower surface of the contact pusher 9122 and come into contact with the IC device 100 when pressed. In the electronic component inspection apparatus 1, the temperature of the IC device 100 may be a temperature obtained by adding a predetermined correction to the temperature detected by the temperature sensor 916 in consideration of the thermal conductivity of the heater block 9121 and the contact pusher 9122. .

  As described above, in this embodiment, the temperature sensor 916 is embedded in the heater block 9121, but instead, the temperature sensor 916 may be embedded in the contact pusher 9122, which is the IC device 100. It is considered that the temperature detection accuracy will be improved. However, as described above, since the contact pusher 9122 is a member that is appropriately selected depending on the type of the IC device 100, if the temperature sensors 916 are disposed in the contact pushers 9122, the temperature sensors 916 are included in all the contact pushers 9122. The cost must be increased. Therefore, if the purpose is to reduce costs, the temperature sensor 916 is preferably arranged in the heater block 9121 as in the present embodiment.

  The temperature sensor 916 is not particularly limited as long as the temperature of the IC device 100 can be detected. For example, a Pt sensor such as a platinum sensor, a thermocouple, a thermistor, or the like can be used. Note that when the IC device 100 includes a thermal diode or the like, the temperature sensor 916 may be omitted, and the temperature of the IC device 100 may be detected by the thermal diode.

-Heat sink-
As shown in FIG. 2, the heat sink 914 is provided between the base 911 and the heater block 9121 (a gap formed by the member 917). The heat sink 914 is fixed to the heater block 9121 using, for example, a brazing material such as solder, and is thermally connected. Since the brazing material is excellent in thermal conductivity, it is possible to effectively perform the thermal connection by fixing the heat sink 914 to the heater block 9121 using the brazing material.

  As shown in FIG. 5, the heat sink 914 includes a plurality of fins 9141. The plurality of fins 9141 each extend along the X direction and are arranged at an equal pitch in the Y direction orthogonal to the X direction. By providing the fins 9141, the surface area of the heat sink 914 is increased and the heat dissipation effect is improved. The configuration of the heat sink 914 (particularly the shape of the fins 9141) is not particularly limited as long as the heat of the heater block 9121 can be radiated. For example, a configuration in which a large number of columnar fins are arranged in a matrix or a staggered pattern It may be.

  Further, the heat sink 914 is provided in contact with the base 911. In other words, a gap is formed between the heat sink 914 and the base 911. Thereby, heat exchange between the heat sink 914 and the base 911 is suppressed, and the heat dissipation effect of the heat sink 914 is improved. The size of the gap can be easily controlled by adjusting the height of the member 917.

-Injection nozzle-
As shown in FIG. 2, the injection nozzle 915 is positioned on the + X direction side with respect to the heat sink 914 and is provided side by side with the heat sink 914. The injection nozzle 915 has a flow path 9152 for the cooling gas G and an injection port 9151 connected to the flow path 9152. A cylinder 986 is connected to the flow path 9152 via a valve 985, and the cylinder 986 is filled with a cooling gas G. When the valve 985 is opened, the cooling gas G is injected from the injection port 9151 toward the heat sink 914. In this way, the IC device 100 is cooled via the heat exchanging portion 912 by cooling the heat sink 914 with the cooling gas G. Thereby, the IC device 100 can be cooled with a simple configuration.

  The injection nozzle 915 has a columnar shape extending in the arrangement direction of the base 911, the heat sink 914, and the heat exchanging unit 912 (Z-axis direction in a natural state where the swinging mechanism 93 does not act). The cooling gas G is sprayed by diffusion (injected radially). Thereby, the injected cooling gas G can be brought into contact with a wide range of the heat sink 914 while downsizing the injection nozzle 915. Therefore, the heat sink 914 can be effectively cooled, and the first hand unit 91 can be downsized. As will be described later, the four first hand units 91 can be arranged at a narrow pitch.

  In the present embodiment, the injection nozzle 915 is positioned on one end side (+ X direction side) in the extending direction of the fin 9141 with respect to the heat sink 914, and the cooling gas G is injected toward the heat sink 914 from that position. To do. In other words, the heat sink 914 has the fins 9141 along the flow of the cooling gas G. Therefore, the cooling gas G can be efficiently introduced between the adjacent fins 9141, and the function of cooling the heat sink 914 is improved. Note that while the cooling gas G is diffused and injected from the injection port 9151, the plurality of fins 9141 are arranged in parallel with each other, and the distance from the injection port 9151 increases as the distance from the injection port 9151 increases. The inclination of the fin 9141 increases with respect to the flow. As the inclination increases, the cooling gas G is less easily introduced between a pair of adjacent fins 9141. However, after the introduction, the cooling gas G becomes a turbulent flow, and the cooling effect is improved accordingly. Therefore, the entire area of the heat sink 914 can be cooled relatively uniformly, and the IC device 100 can be efficiently cooled.

  Further, the spray nozzle 915 is fixed to the base 911 via a fixture, and the relative position with the heat sink 914 is kept constant. Therefore, the cooling gas G is stably injected to the heat sink 914, and the heat sink 914 can be stably cooled. In particular, in the present embodiment, the heat sink 914 swings together with the heat exchanging portion 912 by the swing mechanism 93 and the posture thereof changes irregularly, so that the relative position between the injection nozzle 915 and the heat sink 914 is kept constant. Otherwise, the heat sink 914 cannot be stably cooled.

  Moreover, as shown in FIG. 6, the injection cross-sectional shape of the cooling gas G injected from the injection port 9151 can be made into the shape which suppressed the breadth of the Z direction. That is, the width a in the Z direction can be made smaller than the width b in the direction orthogonal to the Z direction. Therefore, the cooling gas G can be efficiently supplied to the heat sink 914. However, the injection cross-sectional shape of the cooling gas G is not limited to this, and the width a and the width b may be substantially equal as shown in FIG. By making the injection cross-sectional shape of the cooling gas G the shape of FIG. 7, the shape of the injection port 9151 is simplified compared to the case of FIG. 6.

  The injection nozzle 915 has been described above. The cooling gas G is not particularly limited as long as the heat sink 914 can be cooled, but is a compressed gas (a gas compressed at a pressure larger than atmospheric pressure (for example, about 10 times atmospheric pressure)). Is preferred. Thereby, the heat sink 914 can be efficiently cooled. The cooling gas G may be laminar or turbulent, but is preferably turbulent. Since turbulent flow has a higher effect of transporting and diffusing heat than laminar flow, the heat sink 914 can be cooled more efficiently by injecting the cooling gas G to the heat sink 914 as turbulent flow. it can. Here, the “turbulent flow” means an air flow having a Reynolds number larger than the critical Reynolds number, and the “laminar flow” means an air flow having a Reynolds number smaller than the critical Reynolds number.

  Further, the cooling gas G is not particularly limited, but for example, air is preferably used. As a result, the handling becomes simple and the cooling cost can be reduced. Further, as the cooling gas G, it is also preferable to use a gas having a higher thermal conductivity than air such as hydrogen or helium. In this case, since the gas is more expensive than air, the cooling cost is increased as compared with the case of air, but the cooling performance is improved. That is, by using hydrogen, helium, or the like, the IC device 100 can be cooled at a higher speed. By using a refrigeration cooler (refrigeration dryer) and using cooled compressed air, the cooling performance can be further improved.

-Member-
As shown in FIG. 2, the member 917 is located between the base 911 and the heat exchange unit 912, and forms a space for arranging the heat sink 914 therebetween. As shown in FIG. 5, the member 917 has a columnar shape and is disposed at the four corners (outer peripheral edge portions) of the heater block 9121. Further, notches 9142 are formed at the four corners of the heat sink 914, and at least a part of the member 917 enters each notch 9142. Thereby, the heat sink 914 can be arranged in a wider range on the upper surface of the heater block 9121. Therefore, the cooling effect of the IC device 100 is improved.

  The member 917 is made of, for example, a resin material and has heat insulation properties. Since the member 917 has a heat insulating property, heat exchange between the heater block 9121 and the base 911 via the member 917 is suppressed, and the IC device 100 can be efficiently heated and cooled, respectively. In the present specification, the “heat insulation” specifically means that the thermal conductivity is about 2 W / (m · k) or less.

  As shown in FIGS. 5 and 8, a pair of notches 9171 and 9172 are formed in the central portion (a portion excluding both end portions) of the member 917 in the height direction so as to face each other via the central axis. . The bottom surfaces of the notches 9171 and 9172 are flat surfaces parallel to each other. Due to the notches 9171 and 9172, the width c in the opposing direction of the notches 9171 and 9172 of the member 917 is shorter than the width d in the direction orthogonal thereto. The member 917 is fixed to the base 911 and the heater block 9121 so that the notches 9171 and 9172 are aligned in the Y direction. Thereby, in the XY plan view, the width (= c) of the member 917 in the direction orthogonal to the flow direction of the cooling gas G is smaller than the width (= d) in the direction along the flow direction. , 9172 can be reduced compared with the case where there is no 9172, the amount of the cooling gas G blocked by the member 917 can be reduced. Therefore, the effect of cooling the heat sink 914 is improved.

  The member 917 is formed with a through hole (hole) 9173 that penetrates the side surface. The through hole 9173 functions when the member 917 is fixed to the base 911 and the heater block 9121. As shown in FIG. 8, female screws are formed at both ends of the member 917, and the member 917 is fixed to the base 911 and the heater block 9121 by screwing. As described above, since the orientation of the member 917 is fixed, it is preferable to keep the member 917 in a predetermined direction when screwing the member 917 to the base 911 and the heater block 9121. It is difficult because the direction of the member 917 may change due to tightening. Therefore, when screwing, the rod-shaped tool 2000 is inserted into the through-hole 9173, the orientation of the member 917 is adjusted using the tool 2000, and the rotation of the member 917 is prevented. Can be solved. Therefore, fixing of the member 917 (assembly of the first hand unit 91) can be easily performed.

-Control unit-
As illustrated in FIG. 9, the control unit 918 controls the driving of the heater 913 and the injection nozzle 915 (that is, the valve 985) based on the temperature of the IC device 100 detected by the temperature sensor 916, and the temperature of the IC device 100. Is maintained within a predetermined temperature range (for example, set temperature ± 2 ° C.). By performing such control, the IC device 100 can be inspected at the set temperature. In particular, the temperature rise due to self-heating of the IC device 100 can be canceled and the temperature of the IC device 100 being inspected can be kept substantially constant, so that the IC device 100 can be inspected more accurately. .

  For example, after the IC device 100 is pressed against the individual inspection socket 61 with a predetermined inspection pressure by the first hand unit 91, the control unit 918 drives the heater 913 and detects it with the temperature sensor 916. The IC device 100 is heated to a set temperature (for example, 100 ° C.) based on the temperature of the IC device 100 to be processed. When the temperature of the IC device 100 is stabilized near the set temperature, the IC device 100 is driven to start inspection. Then, the control unit 918 performs feedback control according to the temperature of the IC device 100, and maintains the temperature of the IC device 100 near the set temperature.

  Specifically, when the IC device 100 exceeds a set temperature due to self-heating, the control unit 918 stops driving the heater 913 and opens the valve 985 to inject the cooling gas G from the injection nozzle 915. On the other hand, when the temperature of the IC device 100 is lowered below the set temperature due to cooling by the cooling gas G, the control unit 918 closes the valve 985 to stop the injection of the cooling gas G and drives the heater 913. By performing such feedback control, the temperature of the IC device 100 under inspection can be stabilized near the set temperature.

Note that the method of controlling the heater 913 and the injection nozzle 915 of the control unit 918 is not limited to the method of switching between driving of the heater 913 and injection of the cooling gas G as described above. For example, the control may be such that the cooling gas G is injected when the IC device 100 exceeds the set temperature while the heater 913 is always driven during the inspection. Further, during the inspection, the output of the heater 913 and the injection amount of the cooling gas G are changed according to the temperature of the IC device 100 in a state where the driving of the heater 913 and the injection of the cooling gas G are always performed.
