LED lamp bead because of energy saving, low carbon environmental protection, no strobe, no radiation, high brightness, low heat advantages are gradually replacing the fluorescent lamp on the market, its application scope is expanding,although LED has many advantages, if the production or operation is not appropriate,there will be LED strip use fault phenomenon. LED lamp strip manufacturers also begin to pay more and more attention to the problem of production quality, then what equipment can be used for LED lamp strip backlight detection? Unicomp Technology here recommended AX8200L LED strip backlight detection equipment.

Any one has experience over solder voids in oscillator capacitor joint could result in high phase noise during the digital performances test? The noise signal was gone after solder touch up. What could be the root cause of the high phase noise?

I haven't experienced this problem, exactly, but I have had issues with noise in digital circuits that appear to have gone away with touch up. The problem was that the customer blamed the noise issue on the solder quality, and he pointed to the fact

I�m working in Solder paste manufacturing industry and my customer has complained the void issue on BGA pad. I�m internally conducting the void test on BGA pad in my Lab. I used OSP furnish board with Sn/Pb and /or lead free component using Lead free

Just to add to my comments,solder joint voids do occur in LGA. Voids in LGA can be larger due to geometry and greater ratio of flux to solder. IPC-A-610D specifies a greater than 25% voided area is a defect for BGA, however, it does not specify the d

Yes, we assembled a lot of QFN in the last years, but we don't have a X-ray machine by ourself, so we cant't inspect each device. This type LGA was designed on a prototyping board of our customer so we would validate our LGA reflow process and a rese

Good. This is the right way to profile. Let me ask you, have you anytime soldered QFN componets on your boards? The concept of LGA soldering is similar to that used for a QFN package. QFN soldering also exhibits void formations, and is an inherent pr

Dear Sachu_70, During the tests we also checkt other devices, there are a few small voids visible, but they are marginal. We only see large voids in this device. During the testruns we tried several reflow profiles, but without large succes.
