In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.
Let’s face it friends, everything is moving toward surface mount components. We’ve seen quite a few features here that cover using stencils to populate boards and using ovens to reflow. Jack has put t...(view more)
miika.kirvesThe company I work for is looking to install a new SMT line. We currently use Assembleon equipment but we are also looking at Sony. I have not seen any information on how well Sony machines perform. I...(view more)
2B labsHi, During SMT process, i found that solder splash on the gold pad. The distance between the COB pad with component pad is about 1.25mm. My question is what material can used to cover the COB pa...(view more)
akiraHi, This is a little embarrassing asking this question, as I think I am profiling our oven incorrectly. I have been using the profile based on the solder paste specification, however we ha...(view more)
Pierre MainardiQFN assembled on a PCB indicates paramteric fails when tested. When the QFN on PCB is reflowed a second time, it recovers and passes testing. Visual, X-ray inspection revealed no anomalies. Cross-sect...(view more)
yesyesPurchasing extra components to keep surface mount technology (SMT) production lines running is the main focus of attrition. During SMT manufacturing some components will be lost. Attrition ensures tha...(view more)
Bartlomiej HydrynskiHello. smtguys Is there any body who has or know the in -line machine inspecting the solder paste after printing. what i only know is the centry 2000 made by the CYBER OPTICS. anything else ? for insp...(view more)

ElhanafyI have been asked to do a justification for a piece of equipment. Can anyone e-mail a format or example of a complete justifictation so I don't have to recreate the wheel. Thanks(view more)
drkaHi, We have a climatic controlled assembly area, with a constant temp of 22 deg C and a relative humidity of 40 - 50 %. What I would like to ask is how should I approach a situation when the hum...(view more)
