Hi Stella, Relief etch the higher area. Provide the cad data file of the higher area to your stencil vender and tell them you want a 0035m relief on the bottom side of the stencil. This should correct your problem.

Recently, we are attempting to print so but result in solder shorts due to extra heights. Appreciate any helpful info. thanks stella yap *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** ------------------ RFC822 Header Follows ------------------ Received: by smtp2.space.honeywell.com with SMTP;17 Oct 1996 07:36:22 -0400 Received: from IPC.ORG by fl51mail.space.honeywell.com with SMTP (1.38.193.5/16.2) id AA23363; Thu, 17 Oct 1996 07:45:34 -0400 Received: from ipc.org by simon.ipc.org via SMTP (940816.SGI.8.6.9/940406.SGI) id GAA06712; Thu, 17 Oct 1996 06:30:33 -0700 Resent-Date: Thu, 17 Oct 1996 06:30:33 -0700 Received: by ipc.org (Smail3.1.28.1 #2) id m0vDq3g-0000SUC; Thu, 17 Oct 96 05:52 CDT Resent-Sender: [log in to unmask] Old-Return-Path: <es500yap@pts7> Date: Thu, 17 Oct 1996 18:27:59 +0800 From: es500yap@pts7 ( YAP CHOW LAN) Message-Id: <[log in to unmask]> To: [log in to unmask] Subject: ASSY : paste printing Cc: es500yap@pts7 Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Md5: tVUBPi5aRbDS5VVjPwvCQA== Resent-Message-Id: <"mdFWw2.0.RVC.8_WPo"@ipc> Resent-From: [log in to unmask] X-Mailing-List: <[log in to unmask]> archive/latest/6943 X-Loop: [log in to unmask] Precedence: list Resent-Sender: [log in to unmask] *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
