We are looking to possibly counterbore a coule of thru holes in one of our PCBs. We would counterbore the top side, and the only trace is coming out of the bottom side. The reason is to mount some LEDs flush with the board. They have some flash wh

Steve - The weakened condition was my concern, and that was why I was asking if anyone had any details on issues that may occur doing this. Do you know of any details behind the risks involved? Qualifying a new LED will take a load of R&D resourc

I don't have any data (haven't tried this), but it doesn't take much thought to see that determining the risks associated with simultaneously applying compressive and rotational forces to the end of the barrel, not to mention chewing up the copper, i

Thank for the feedback everyone. The LED is designed to be soldered 2mm above the board, so that is their rational for allowing that much flash. And a spacer is not going to work because of the height limit of mating parts (I didn't design the boar

Hi Mark, Couterbore is possible in two way's during PCB Manufacturing. Couterbore plated and non-plated. Meaning that the entire hole will either have to be Plated or Non-Plated. Prefered Methode is Plated, to accomplish this your PCB house would

Hi, We have two complete SMT line and in this department we use conveyors for board manipulation. Concerning the wave area we are not full efficiency and I have to look for conveyors and bar code reader to make board manipulation an automatic proces

Thanks Bill and Dave for your help, Sorry Dave if I didn't search for information in archives. After wave process we have 2 ICT, 2 AOI machines 4 PVA conformal coating machine that will be use on 3 different lines. The quind of automation I want to

Hello Mika, I just checked a windmill and a test nozzle we have on the bench. The useful travel of the nozzle before the risk of the crosspin getting stuck in the loading gate is 1.5mm, if it gets stuck it is the nozzle is 1.7 up. If the cross pin is

Many Thanks to You all. I think we should be ok with the majorty of our cap's if we set the comp. thicknes to 0.2 mm less than the actual size to be able to compensate for the variable thicknes from different wendors for a certain component. Do You
