I have many PCBs that use an AVR in SMD packaging, and since I frequently change the firmware in prototype boards, I'm trying to come with the best solution to program the AVR quickly and easily. The first approach was to have a standard header (2x5

Hello Dears, I'm a small CS Engineering at Taiwan.There are some problem on DIMM connector area with poor solderability at ODM. It was random on Dimm connector area and the SMT area is fine. At the same time, there were other PCB vendor's product whi

Westshored; Not sure how helpful I can be as there are details missing from your description. So I will try and give you some requirements that may help us sort this out. The Speedline UPGR was UPGR-026 and 027, depending on the machine type. The

Hi all, We run an old Seho 1135C wave solder with a 63/37 pot at 250°C. It has been running well for a couple of years but we have noticed lately that all of the larger pads (terminal blocks, transformers, etc.) require additional solder to be appli

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

Just buy a separate machine to apply paste. You'll be able to run faster, (by doing more at the same time) and you can probably find an air-over-syringe system for less than $2000USD. At the end of the day, that's probably less than you'll spend in t

In my past life, I worked at a CM that used Mirae "Meridian" machines Universal Instruments "Genesis" machines. The universal instruments machines were much, much faster. What sort of head configuration did your Advantis machines have? The 30 spindl
