48.2.1.3 Vacuum Pickup Device. This is generally a silicone rubber suction cup or a solid metal tube nested within the nozzle and connected to a vacuum pump. Silicone is chosen for its heat resistance and compliance. The vacuum can be toggled on and off to pick up and release a component. The vacuum pickup device serves two purposes. First, it is used to remove a component from the circuit board once the component has been heated by the hot-gas to the point of reflow. Following dressing of the repair site, the suction cup is used to hold the replacement component rigidly during lead-to-pad alignment and placement steps. 48.2.1.4 Adjustable Stage. This permits alignment of the nozzle to the PWB in the x-, y-. and q-axes. It is important for component removal but even more critical for component replacement and alignment of component leads to PWB bonding pads. 48.2.1.5 Vision System. This is used to align component leads to PWB bonding pads manually. Usually a split-image video system is used to view both component leads and board bonding pads simultaneously. The images are superimposed and the operator manually adjusts them for the best lead-to-pad alignment. 48.2.1.6 Computer Control. This is the heart of most hot-gas machines. It monitors and controls the various operations of the system, such as preheating and thermal profile. The rework engineer programs the profile manually.

Hot-Gas Repair Process 48.2.2.1 Thermal Profiling. As with any reflow process, whether for first-pass build or for repair, it is necessary to construct a thermal profile board as previously described to assess the impact of heating and to ensure that the heating is adequate, in accordance with the thermal

limits described by the solder paste manufacturer, the component specifications for thermal exposure, best solder wetting, and minimized intermetallic formation In the case of repair, a dummy board is used with thermocouples attached to the component to be removed and critical adjacent components to ensure that reflow conditions are correct 48222 Component Removal Preheat As discussed previously, preheating may be necessary to overcome the thermal mass of the assembly and to ready the board for the reflow step Preheat temperature is set well below the reflow temperature of the solder alloy in use to confine reflow to the device being removed or replaced and to discourage widespread reflow in the vicinity of the removal or repair 48223 Reflow and Removal The same considerations apply for this as for any reflow step.

The ramp, soak, peak temperature and time above liquidus are dictated by the solder alloy used and should be roughly the same profile parameters that were used for the initial assembly of the board Once the component has reached complete reflow, the vacuum pickup tool is engaged and the component is lifted vertically Care should be taken to minimize the time above liquidus to minimize intermetallic compound thickness 48224 Site Dressing Following component removal and while the board is still hot, the solder lands on the PWB can be prepared for component replacement by means of a hand soldering iron and a braided copper solder wick or a solder vacuum machine that simultaneously heats the pad by hot gas and vacuums up any excess solder.

During the component removal step, solder surface tension capriciously allows some of the solder from the joint to be removed with the package leads and some to be left on the bonding pads In the case of area-array packages (BGA, ceramic ball grid array [CBGA], etc), the ball may remain with the package or with the land This can make solder land dressing a labor-intensive operation Care at this step is critical for success in resoldering a fresh component and for reliability The dressed bonding pads should be smooth so as not to interfere with fresh component placement 48225 Part Bake-Out As with first pass soldering, it is important to observe rules concerning component bake-out to remove any absorbed moisture and preclude part cracking during the reflow heating cycle Guidance for part baking can be found in IPC/JEDEC J-STD-0331 4822.

Kate Washington was so excited about the possibilities of her project. She stood in front of the community and explained the role of the stakeholders, the costs of the materials, and the potential income produced by the project. She was particularly enthusiastic when she spoke about the new day care center. Still, for some reason, the audience seemed restless and uninterested. Having no idea what was making them uncomfortable, she hurried to reach her conclusion and ended her speech. A few members of the audience left grumbling, and one of her listeners came up to the podium to ask a question. As soon as Kate answered the question, she realized, to her embarrassment, what had happened.

6 Solder Paste or Flux Deposition Although this is not part of the hot-gas station, it is part of the hot-gas work cell and needs to be discussed For most SMT components, solder paste is added to either the board or the component to effect a reliable solder joint for component replacement This is generally done by ministencil similar to what is used for SMT solder paste deposition, but on a smaller scale; the stencil is only slightly larger than the component footprint The paste is pushed through the stencil apertures with a razor blade or a miniature stainless-steel squeegee Programmable syringe-dispenser machines are sometimes used, but solder paste is known to separate when under pressure, ie, solder alloy separates from the solder flux Choosing the largest needle bore, slowest dispense rates, and lowest pressures will help to mitigate paste separation.
