Just for your reference. If you need to check for surface contamination, then we shall go for microscope inspection at different modes. But this will not reflect on actual PCB performance. Solderability test will still a good option if PCBA is expe

Dear WRS consideration for buying SMT equipment is likely you buy a vehicle, you must consider many things, after sales services, machine easy to do model change, accuracy,cheap, mostly machine use in your region. etc. I also run production for LCD

We are currently using the F1. We've had it for a couple of years now and overall we are happy with it. We did have some issues with the software crashing but after replacing the PC several times we seem to have found a stable platform. Also the conv

Who Cares... Mix Away! Although you should not mix different Solder Pastes' together in a container or on a stencil (Mostly due to the flux, although solder sphere size and shape could cause an issue), mixing solder brands or chemistries on a board

The 5 thou standoff of your SOIC is probably the minimum. We wouldn't be surprised to see 10 thou. With this, you could have maybe a 6 thou gap between printed solder paste and the bottom of the heat slug. So, you're expecting the rabbit ears of p

Hello. We encountered a SMD problem on PCB. It is that the lead of photocoupler is shifted after reflow and don't meet the minimum requirement of side joint length. I know this is a defect but what i want to hear the reason and the solution to prev

Hello, I'm printing adhesive in one of my products using 0603 components, and I'm facing some issues when PCB goes through Wave Solder, I'm checking the right amount of adhesive & termal profile, but missing components still being my headache, I know

Hi Rem Woo, ur board is such long one,7'. Our PCB is only 2' long but 3.5kg weight b4 solder. We use wave machine to solder it and PCB was sit on the pallet. all PCB side lengths are pressed by clamps. PCB was flat just after wave, however there was

Tom, If you need the parts... I can quote and supply them.. A good tradesman can change these parts. You do not necessarily need a Yamaha trained guy to do it. The only issue issue after the exchange of the parts is calibration of the machine, which
