Mounting on printed circuit boards When mounting a transistor on a printed circuit, it is assumed that lead wires will be processed or reformed due to space limitation or relations with other components. Even if no such special processing reforming is conducted exercise care on the following points : (a) Make the spaces of lead wire inserting holes on the printed circuit board the same as those of lead wires on a transistor. (b) Even if The spaces are not the same, do not pull the lead wires or push heavily against the sensor element. (c) Use a spacer for form a lead maintain space between a sensor and a printed circuit board, rather than closely contacting them with each other. (d) When forming a lead prior to mounting onto a board - Bend the lead at a point 3mm or more apart from the body(Lead root). - Bend one lead wire after securing the other lead wire. (near the main body) - Keep space between the sensor main body and and a fixing jig. - When bending the lead along the jig, be careful not to damage it with an edge of the jig. - Follow other precautions described in respective standard (e) When mounting a sensor onto a heat sink - Use the specified accessory. - Drill threaded holes on the heat kink as per specifications and keep the surface free from burrs and undulations. - Use KEC’s recommended silicon grease. - Tighten the screw within the specified torque. - Never apply a pneumatic screwdriver to a transistor main body. (f) Do not bend or stretch the lead wires repeatedly. When pulling in the axial directions, apply 500g or 600g power, depending on the shapes of lead wires. 2. Soldering When soldering a sensor to a printed circuit board, the soldering temperature is usually so high that it adversely affects the sensor. Normally, tests are conducted at a soldering temperature of 265 for 10 seconds or 300 for 3 seconds. Be sure to complete soldering procedures under these conditions of temperature and time. Be careful to select a type of flux that will neither corrode the lead wires nor affect the electrical characteristics of a sensor. The basic precautions for soldering procedures are as follows : (a) Complete soldering procedures in a time as short as possible. (b) Do not apply stress to a sensor after soldering by correcting or modifying its location or direction. (c) For a sensor employing a heat sink, mount it on the heat sink first: then solder this unit to a printed circuit board after confirming that it is fully secured. (d) Do not directly solder the heat-radiating portion of a sensor to a printed circuit board. (e) In flow solder jobs, sensors are apt to float on the solder due to solder surface tension. When adjusting the locations of sensor, be careful not to apply excessive stress to the roots of the sensor lead wires. (f) When using a soldering iron select those which have less leakage, and be sure to ground the soldering iron. 3. Cleaning a circuit board After soldering, circuit boards must be cleaned to remove flux. Observe the following precautions while cleaning them (a) When cleaning circuit boards to remove flux, make sure that no residual reactive ions such as Na or Cl ions remain. Note that organic solvents react with water to generate hydrogen chloride and other corrosive gases which can degrade device performance. (b) Do not rub the indication marks with a brush or one ’s fingers when cleaning or while a cleaning agent is applied to the markings. (c) There are ultrasonic wave cleaning methods which offer a high cleaning effect within a short time. Since there methods involve a complicated combination of factors such as the cleaning bath size, ultrasonic wave vibrator output, and printed circuit board mounting method, there is fear that the service life of airtight seal-type sensors may be extremely shortened. Therefore, as far as possible avoid using the ultrasonic wave cleaning method. - Basic requirements of ultrasonic wave cleaning method. Frequency : 27~29kHz Output : 300W or less (300W/ or less) Recommended solvents : Refer to details above Cleaning time : 30seconds or less Application circuit The Pressure sensor is designed to convert a voltage by means of constant current drive and then, if nesessary, it amplifies the voltage for use. The circuit shown below is a typical example of a circuit in which the pressure sensor is used. Pressure Sensor Amplifier Circuit Unit Constant Current Circuit Unit OP AMP OP AMP OP AMP
