BGA Laser

Click here to enlarge image

Turbo II is an Nd:YAG laser used to manufacture stencils for printing solder paste on printed circuit boards. The requirement for accurate holes, cut rapidly, has reportedly been problematic for traditional laser cutting systems. When a laser performs cuts on BGA-type apertures, it makes a series of holes by initiating small-segmented cuts. These circular cuts are not entirely round and, in theory, a small imperfection or deposit is left each time the shutter interrupts the laser beam, impeding the paste flow through the stencil and resulting in open solder joints. This laser system makes circles by optically cutting past 360°. Instead of moving the laser or material, a rotating optic moves the beam, cutting round hole sizes between 80 and 800 µm.

Thermal Compound Application

Thermal Compound Application Technology (T-CAT) is designed for quick, easy, cost-effective application of heat-dissipating thermal compounds to critical components — chips that cannot afford to fail from of excessive heat build-up. This technology replaces manual application of thermal compounds. Built around a self-registering tabletop printer, T-CAT ensures proper alignment of multiple components. Precise laser-cut stencils, with raised walls to isolate the leads, ensure that the body of the component receives the compound, not the critical leads. The result is fast, efficient compound application, less labor on the front-end and a reduction in rework. Integrated Ideas & Technologies Inc., Coeur d'Alene, Idaho, For free data, enter 167 at

Reworkable Underfill Encapsulant

CN-1432 is a reworkable underfill encapsulant designed for CSP and BGA encapsulation. CSP's and BGA's are not normally encapsulated, but mobile phones and other handheld devices require encapsulation of these components to survive drop tests and repeated keypad actuations. Removal of defective CSP's and BGA's is accomplished by heating the component and the underfill encapsulant to 220°C. Underfill encapsulant residues can be easily brushed or scraped off. CN-1432 offers a viscosity of 4,500 cps at room temperature, making it easy to dispense. It is also fast flowing, capable of flowing a distance of 18 mm, with a single dispense, in 15 seconds. After flow is complete, the encapsulant can be cured in an in-line oven, in 5 minutes at 165°C. Zymet Inc., East Hanover, N.J., For free data, enter 169 at

This company designs thermal shield solutions in various sizes and models to fit individual shielding needs. The standard thermal shield is 1/8″ thick and is shipped with all SlimKICs. The 1/4″ shield is available and reportedly offers better thermal protection than the standard shield. The next shield type, the Low-Rider, is a SlimKIC cover for processes with low height clearance where the standard shield is too tall to pass through. This shield reportedly can be used in combination with other shields to provide added thermal protection. The Lead-free shield is the largest thermal shield and is designed for long duration — 30 to 60 minutes. Like both the standard and 1/4″ shields, this is capable of withstanding temperatures up to 300°C. KIC, San Diego, Calif., For free data, enter 164 at
