Electronics Forum | Thu Jan 04 06:29:09 EST 2007 | bT_Solutions

Thanks SWAG. I figured there must be a way to import data. I beleive right now, the SMT operators where I work are manually making the programs right on the GSM, which depending on the assembly, could take up to a full 8-hour shift (especially when t

If you need any info about the 4785, let me know. If you understand Perl I'd be happy to send you the software I wrote for 4785 program generation. Mine is based around PanaPRO but it would at least give you a very simple optimization routine if

Set Up Guy, I am not sure if the COB you are refering to means Circuit on Board . If yes, this process also include SMT . Package is a combination of some passive components and bare die. Passives are normally attached thru SMT using solder te

Hi, Does anyone know where to purchase the connectors? Specifically bulkhead connectors or PCB mount connectors. I am thinking about doing a general purpose SMEMA box that has a Basic Stamp in the core, and some buttons so I can use it for general

All, We have ran a few revisions of a New Product which is a tracking device using satellite navigation. The protos went well but now they have added a shielding can. We place 2 of these to cover the Frontend of the PCB. The test guys are having d

Thanks both of you for responding. I am using a protoype reflow oven. It uses a programable controller to ramp the temp up. It has convection and radiative heating. Ultimately yes, I would like to use a vacuum furnace like the sst but it is not c

SMT machine shift to China

The dumbest thing I read was the response to me saying people should not automatically send product to China. I was told not to bury my head in the sand. A lot of companies are being lemmings and taking it for granted it's best to send a product to C

We are now using solder paste(OM325) and I have some problems on the folowing process: 1. We use the solder paste softer(Malcom SP-1) to warm-up for 20 mins, when it just take from refrigerator. Is there any problems for solderpaste performance? 2.

Solder paste handing

Yes, it can evaporate. My point was manufacturers suggest cool storage to avoid seperation. I guess if the flux does seperate and get pushed to the top it could have a greater chance to evaporate. I have only seen such seperation on year + old jar

Contractor mantra: * Profile is good * Boards are bad On profiles, the key question is: where did you take the profile? We�d guess cracked connections are giving the intermittent test results when pressing on the components. You use acoustic micro
