hi all. I am looking for a oven which can cure the conformal coating providing heat and the humid atmosphere. I am looking for a temperature range of 60 deg C to 80 deg C and a humidity range of around 80%. Can anybody refer to me the right vendors

Sr. Assuming you are processing the garden variety 63/37 paste on FR4 substrates, a good starting point is to plan for 3.5 to 4.5 minutes of process time on the board. If you measure the total heated length of your oven and you use the range above,

Good Morning Everyone, Could someone please tell me what the acceptable range is for HASL plating thickness. We have some raw boards with plating thicknesses ranging from 3-4 mils on a fine pitch QFP. We are expeiencing bridging at this location an

Nippy, This is exactly what we are seeing. The exessive pads are all on one side of the board. This is a 10 up panel 5x2. All of the QFP's on one side on the panel are not releasing or are not gasketing and causing bridging. So the defects are rangi

Hi All, We are looking for a multifunctional P&P capable of 20mil pitch and 0402 at a few kpph, preferably fully automatic. We need to stay in the $10K - $15K range. Are we kidding ourselves? And if so, what can we get in this price range? Thank

Most board fabricators define a range of processes parameters that are routine for their plant set-up and methods. Look here http://www.divsys.com/ServicesProducts/PCB/MfgCapabilities.asp for an example. If you don't define your requirements, you'

Lower RH = more static build-up on production floor = greater chance of ESD damage to product. Primarily, I think your SMT print job can be affected by RH which could cause defects like the ones you mention. Look at ANSI/ESD S20.20 for more info an

We are starting up a new clean room for SMT production and wondering if anyone is aware of any guideline for operating humidity and temperature ranges for the room. We know that the MSD's will prefer it to be dry and cool. However, there are other f

Consult your solderpaste manufacturer's data sheet for this information- peak temp range, TAL range, etc... Your profiler may be able to have solderpaste mfr's parameters included in profile data reporting- ECD profilers can import solderpaste data a
