The cable required for the Thinline has to work as a true RS232 interface as the unit uses all the capabilities of RS232. You will have several problems with substitutes. These cables (part number e00-2787-26) are still avaliable from ECD, the home o

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

Im qualifying a new PCB. I run 2 diff supplier. Supplier A has Zero failure. Supplier B has 4 failure all having Lifted PAD on Bga same location and same location pads that lifted. How can I prove that the PCB have problem? Input : Both run in same o

Hi all, I would like to know what sort of peak temps people are seeing during reflow - I understand that there are many variables that contribute to this but there should be an average through out all the profiles. We are still seeing issues with d

We are using VP on all of our lead free assemblies. 1. We are getting great, very repeatable results. 2. The profiles were created during the implementation of the equipment and we only change 3 parameters for each assembly processed. Heater power,

LISTEN this is quite a soar subject to me.i have old wounds too from these capacitators and argued with the darn engineers at my old place of employment that if they only stuck to wave and through � hoel stuff, they wouldn�t be in this pickle. IF the

The pad size is okay. I have also requested the manufacturer's recommend reflow profile. I have seen some issues with 0402 caps that we run also but for the most part solder paste does okay. I think the cap issues is stencil related. Still trying to

Asking the part manufacturer for this info would require you to give them the type of paste you use, via hole opening, profile.... etc. That's why they don't have this info. Looks like someone is gonna have to do some old fashion engineering work.

Listen, fancy places and spending lots of money will never replace a good wave profile and a good scrubbing from the garden hose. Get you'r e act together and you need mininimal cleaning of the pallets. Then theywill just clean up well with a littl

my oven has a built in profiler, it works fairly well, but it can not predict changes. my main concern was about the time right before reflow. i know that's where the flux is activated and i was worried that i may be spending too much time at the tem
