The 575 was based on the 570 machine. The 570 was Juki's first laser centered machine. It can do 0402 and ICs with a pitch of 0.65mm or greater. The 575, was a re-vamped 570 that Zevatech came up with. Juki played no part in the 575. Zevatech ad

There is the IPC/JEDEC J-STD-033 that addresses moisture sensitive components. Go to http://www.ipc.org for the standard. Your factory/storage area environment will dictate exposure times allowable. Be mindful of temperature and humidity changes- lik

I'm being driven to create a DFM guidelines document to keep our engineering team and customers from running amok. I've conceptualized an outline and basically know what needs to be covered but would like to plagerize all I can (more for photos/diag

Hi, Try using or creating a simple data collection system using MS Access...Try this idea: operator inspects the board, then scans the PCB barcode. Then enters the fault found using the codes you are using in your sheet. It's a bit laborious but it

Asking the Grid Lok to flatten out the board is like asking the SMT Reflow Furnace to detab the panel. It was not designed to make up for the deficiencies of your fab supplier or your unsuported 1st reflow pass on the the chain conveyor. However, i

You have two choices� Change your paste or beef-up your wash chemical. I�ll let others discuss paste options but as far as wash chemical is concerned, consider chemicals specifically designed for such applications. Zestron is promoting A300 as sui

Sorry about the non SMT post, but I figured that there might be someone with a similar experience out there. We have been having a tough time cleaning the conveyor chains in our wave solder machine. We have been cleaning them in a self cleaning oven,

I agree with above but would like to add: 1. You may want to try something like Bioact SC-10 wipes to clean your stencils. If what your using works good stick with it. Ultrasonic cleaners are expensive, take up room and my experience has not been go

Hi Robert, We've been using a SmartSonic cleaning system for years. We place a lot of 0402's and FBGA components. The system cleans those apertures very effectively. The chemistry used in the cleaning solution is very safe and environmentally fri
