Hi all. I am looking into the implementation of the Chip on Board process with eutactic bonding and the then using either gold or aluminum wire to make wedge type wire bonding. Since I am totally new to this, can somebody guide me thru the process,

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

We are an OEM manufacturer, and are beginning to look at how we will be affected by the ROHS and WEEE directives. As of now we have many questions, and few answers. Does anyone know of a good comprehensive source where one could get information on:

Yikes!! In-line cleaning, to clean cosmetic and benign residues (from a NO-CLEAN) flux... You sure you can't switch fluxes? Another variable with residues is the solder mask. Depending on mask type (glossy, matte, semi-gloss, or semi-matte), will

Hi, Yes, I would hate to resort to cleaning, but the product must be clean. We have been using palettes to keep most of the flux off the PCB, but there is still residue around the connectors. Does anyone suggest a good no clean flux to use with le

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

I run two different waves here one with SAC305 with aqueous flux the other with SN100C and No clean flux. Does anyone see any issues with running product through either machine of course after changing the Flux type? I also only use SAC305 alloy for

Amkor's MLF guidelines are very similar to Actels. 1 to 1 on the stencil to part pad on the I/O pads, 75% with a grid windowpane, 0.125 mm/5 mil stencil. For example, the Actel area ratio for a 0.3 mm sq. pad and 0.125 mm stencil is 0.6 which seems

We are in the process of researching manual or low cost automatic Tape and Reel equipment. I have heard about V-tek and Systemation. I would appreciate if someone can tell me any problems or virtues of theses two brands that have been experienced. Al

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper
