Number 文件编 号:: DI-43-0041 Date 日期 : July 3, 2015 Ver. 版 本: Approved by 审批人: Pg./Pages: 5.0 1 /4 ? 描述 (DESCRIPTION) 1.1 清洁的步骤 CLEANING PROCEDURE 1.1.1 倒入 IPA 到超声波清洗机直到运作的位置,如果清洁水不足够,只要能够完全的淹没所需清洁的物 体,也可以使用。确保要清洁的部分被淹没(IPA 的高度要高于需清洁的部分)。可以使用客户指定 的其它非 IPA 的化学溶剂,但一般用 IPA。 Pour IPA in the ultrasonic cleaner up to the operating level. In event of IPA shortage, machine can be used as long as the item to be cleaned will totally submerge to IPA. (IPA level is higher than the item to clean). Chemicals other than IPA can be used as instructed by the customer but in general, use IPA. 1.1.2 把需清洁的部分放入超声波清洗机中,然后填写表 FP-R-019 Put the item to be cleaned in the ultrasonic cleaner then fill-up FP-R-019. 1.1.8.1 使用 PWB 的放置夹具,将 PWB 垂直放置。如果 PWB 高于 IPA 的清洁的最高水平线, 则用其它的夹具将其水平放置,但有锡浆的一面必须朝下。如果 PWB 太长,则将其斜 放在清洗机中,并用夹具固定,使得 PWB 与清洗槽底部隔离。如果是有一面已经过炉 的双面板,用顶针固定,让有锡浆的一面朝下。 PWB should be in vertical position. Use the PWB holder jig. If the PWB is too high than the IPA operating level, put it in horizontal position but the solder paste side should be at the bottom. Use different holder jig for this purpose. If the PWB was too long, put it in diagonal position with holder jig to elevate it from the solder paste residue. For double sided PWB with one side already reflowed, use the pin holder jig and place it with solder paste side at the bottom. Recommended: Put diagonal to the Ultrasonic box for long PWB. Use slotted holder jig to elevate to the solder paste residue. 推荐: 把较长的 PWB 斜放在清洗槽中,并用夹 具使其与底部隔离。 Recommended: (建议使用) Place in vertical position with slotted holder jig(带夹具垂直位置安放的 PWB) Use Place Recommend to use: 建议使用 Pin Holder Jig 顶针夹具 Not Recommended: Too High Than Operating Level 不推荐: 高于 IPA 运作水平线的 PWB . Recommended: Place it horizontal to the holder jig with solder pasted area at the bottom. 推荐: 用顶针夹具固定的水平放置得 PWB , 有锡浆的一面朝下 DOC-61-011 版本/ Ver.5.0 BRANSON 超声波清洗机的操作指引 BRANSON Ultrasonic Cleaner Operation Instruction Drafted by 备件人: Product Name 产品名称: Checked by 无 NO Doc. Number 文件编 号:: DI-43-0041 Date 日期 : July 3, 2015 Ver. 版 本: Approved by 审批人: Pg./Pages: 5.0 2 /4 注意:清洗前揭掉关键片位的保护胶纸。清洗前没有揭掉胶纸会导致胶带的粘剂粘在片位上,会有潜在的问题。 NOTE: Remove protective tape (kapton tape) on critical pads prior cleaning. Failure to remove the tape prior cleaning causes the tape adhesive to adhere in the pads and cause potential problem. 1.1.8.2 刮刀平放在超声波清洗机的底部。 Squeegee - holder lies flat at the bottom part of the ultrasonic cleaner box. 当使用 IPA 作为清洁剂时,把加热开关打到“ON”状态。如果使用其它的需要加热的清洁剂,则需 要 SMT 工程师在使用之前作出评估 Turn the Heater switch to “OFF” when using IPA as cleaning chemical. Chemical other than IPA, which requires heating, should be studied and evaluated by SMT Process Engineer prior use. 设定时间 Set the timer: 1.1.8.1 PWB = 7 分钟 PWB = 7 minutes. 1.1.8.2 刮刀 = 10 分钟 Squeegee = 10 minutes 机器停下来后,关掉电源。 After the machine stops, shut off the power. 检查是否完全清洁,如果没有,重复操作清洁步骤,可以把清洁的时间延长 5 分钟,如果有必要, 则重复此步骤。 Inspect, if properly cleaned. If not, redo the cleaning procedure by setting the timer to 5 more additional minutes. Repeat this procedure if necessary. 取出物件,晾干它。 Take out the item and let it dry. 1.1.3 1.1.4 1.1.5 1.1.6 1.1.7 1.1.8 对于 PWB : For PWB: 1.1.8.1 单面板未贴片的 PWB:PWB 的一面在纯净的 IPA 池中浸荡 5 次,然后重复另一 面直到完全移去 PWB 上的锡浆。在整个操作过程中要戴手套。 Single sided or bare PWB: Soak dips the PWB five (5) times to the pure IPA basin on the either side then repeat to the other side to totally remove the solder in the PWB. Use gloves while performing this operation. 一面过炉的双面板:PWB 的一面在纯净的 IPA 池中浸荡 5 次,另一面则不需要浸荡 Double sided with one side already reflowed: Soak dips the PWB into pure IPA five (5) times. The units need not to be turn over will soaking. 1.1.8.2 一手用干净布拿住 PWB 板,另一手用风枪吹 PCB 板。 Use airgun to blow the PWB while the other hand is at the bottom supporting with clean cloth. 1.1.8.3 用显微镜或 LSM 检查 PWB 上是否有锡浆残留,确保完全干净。并把清洁的结果记录在 FP-R-019 Check the PWB in the microscope or in the LSM to inspect the PWB if there is any solder paste residue. Make sure it’s properly clean then fill up FP-R-019 for inspection results. 1.1.8.4 如果需要,重新清洁。 Re-clean, if necessary. 1.1.8.5 对于 PWB 的 ACF 片位(清洗前用 kapton 胶纸所保护),重新贴上 kapton 或类似胶纸。在 特殊位置贴胶纸时要加一点力。如果已经贴好,剪断胶带。 (For PWB with ACF pads (protected by kapton tape prior cleaning), re-stick a tape (kapton tape or alike) in the ACF location. Put pressure while applying the tape in particular locations. If already fixed, remove the tape. 1.1.8.6 在显微镜下再次检查 ACF 片位。如有必要重复前面的流程。 Re-inspect ACF locations in microscope. Redo previous procedure if necessary. . DOC-61-011 版本/ Ver.5.0 BRANSON 超声波清洗机的操作指引 BRANSON Ultrasonic Cleaner Operation Instruction Drafted by 备件人: Product Name 产品名称: Checked by 无 NO Doc.

Check the cleaning solvent inside the ultrasonic cleaner before start of every cleaning or washing then record to FP-R-019. 1.3.2 每月更换清洁水,如果有必要则将其更换。一般来说,如果超声波清洁机的底部被残留的锡浆完全 覆盖,或者清洁水因为助焊剂而变得十分黏稠时,则需要更换清洁水。 Every month replace the cleaning solvent on the machine or as necessary as possible. In general, IPA should be replaced if the solder paste residue was almost covering the entire bottom of the ultrasonic box or the IPA become sticky due to flux residue. 1.3.3 清洁水的再利用,把表层的清洁水与底部混有锡浆的清洁水分离开来 For IPA re-use, scope out the IPA in the box. Extra care is necessary so not to disturb the solder paste residue settled at the bottom. 1.3.4 当清洁槽中还有一半的时候,将剩余的倒入泄露槽中,确保清洁槽底部的锡浆残渣完全清洁干净, 如果没有,则再次加入一些清洁水清洁。 Half way of the box, drains the remaining IPA into the sink. Ensure that the solder paste residue be totally remove. Put some IPA into the box to totally drains out the residue. 1.3.5 使用过的清洁水另外放置以待布署和处理。 Used IPA should be placed in applicable container for disposition and disposal. ? 参考文献 REFERENCE DOCUMENTS DI-43-0025 吸嘴清洁操作指引 Nozzle Cleaning Operation Instruction DI-43-0007 锡浆使用和印刷制程 Solder Paste Use and Printing Process 记录 RECORDS FP-I-013 设备、工、治、夹具维护保养校准记录表(应由生产线保管 11 年) Equipment, Tools, Fixtures, Jigs Maintenance Record (Should be kept by Production for 11 years.)
