In addition, the component must be placed on the printed solder paste, the dispensed adhesive, or a combination of the two deposits with a controlled pressure or release distance that does not excessively spread out either material or damages the component package Moreover, the placement machine must execute these tasks as quickly as possible in order to maximize the production volume Lastly, the equipment must be sufficiently versatile to address continually changing electronic packages, specifically dimensions and I/O configurations The change to Pb-free solders does not have an explicit impact on component placement machine technology Indirectly, however, the need for alternative surface finishes on both the components and circuit board fiducials, which have different reflectance characteristics, can affect the performance of the vision systems used to locate accurately both the circuit board and the tooling that delivers the component to the board Several machine types are available.

The turret-style chip shooter and the gantry-style or flexible fine-pitch (FFP) machines have both been used extensively in the assembly of consumer electronics, telecommunications, mainframe and server computers, as well as for lower volume, high-reliability electronic products However, the demands for even higher production volumes as well as the flexibility to change product lines rapidly have caused manufacturers to consider alternative machine architectures that include high-speed stepper motors and optical sensors as well as highly parallel methodologies that place multiple components at the same time 403331 Turret Systems (Passive Devices) The basic turret or chip shooter has been used to place passive components (ie, capacitors, resistors, etc) since the early development of surface-mount technology A photograph of the turret head and schematic diagram of its operation are shown in Fig 4020 Multiple heads are positioned around a stationary, horizontally rotating turret.

A moving feeder carriage positions tape feeders that deliver a component to each head After the part is located in the head, the turret rotates it to a vision processing station where a charge coupled device (CCD) camera acquires an image of the part This image is processed so that the part will be precisely located over the circuit board location As the turret continues rotating, a moving table positions the printed circuit board so that the target location is in position under the turret head to receive the component The part is lowered to the circuit board and released The head rotates to acquire another component, and the cycle repeats itself Listed in Table 403 are general performance characteristics for turret chip placement technology This technology is constantly addressing smaller passive devices (0101 and 01005) as.

75 485 N = 109 lbf 100 Figure 744 shows the performance of bearings when the diametrical clearance, 2ho = 0001 in (25 m) The airflow is proportional to the cube of the bearing clearance so that a reduction in clearance provides a significant reduction in the demand for the compressor power as well as an increase in the radial stiffness The value of the airflow is read on the curve (023 cfm) at the point of intersection of the length (3 in) and diameter (2 in) For a supply pressure gauge of less than 100 lbf/in2, a correction factor is required (indicated at the bottom of Figure 744) This final value of the air flow would be less than the airflow that is available for our design At a supply pressure of 75 lbf/in2, the airflow needed is 023 065 = 015 scfm 00042 m3/min This value is within the capability of the air supply system that is available In addition, the clearance that is chosen is also five times greater than the available manufacturing error In fact, it is possible for us to design a bearing that has a clearance, which is better than the chosen value However, it is always a good idea to design something that is in the middle range and not at the extreme ends Next, it is necessary to verify that the clearance chosen will gives an adequate radial stiffness The stiffness of the bearing is inversely proportional to the clearance where the reduction in radial clearance will increase the radial stiffness This reduction in radial clearance is limited by the cost and the difficulty in manufacturing From Figure 75, it can be seen that the stiffness of an aerostatic journal bearing is constant up to an eccentricity ratio of 05 The aerostatic stiffness, K, can then be defined as.

well as an increased demand for placing bare die (flip-chip) components on more densely populated circuit boards. Equipment manufacturers and users must continually address new package configurations with different I/O geometries. 40.3.3.3.2 Gantry Systems (Active Devices). The gantry-style architecture differs from the turret because the printed circuit board is fixed in place and the moving gantry locates the
