SIP (Session IniTIaTIon Protocol) is a multimedia communication protocol developed by the Internet Engineering Task Force (IETF). It is a text-based application layer control protocol for creating, modifying, and releasing sessions for one or more participants. Widely used in CS (Circuit Switched), NGN (Next GeneraTIon Network) and IMS (IP MulTImedia Subsystem) networks, it can support and be applied to multimedia such as voice, video and data. Business can also be applied to special services such as Presence and Instant Message. It can be said that there is a SIP protocol in the place where there is an IP network. [1-2]
SIP is similar to HTTP. SIP can reduce development time for applications, especially advanced applications. Since SIP based on IP protocol utilizes IP networks, fixed network operators will gradually realize the far meaning of SIP technology for them.
The SOP is the capitalization of the first letter of the three words of the Standard Operating Procedure. The standard operating procedure is to describe the standard operating procedures and requirements of an event in a uniform format to guide and standardize the daily work.
The SOP is an acronym for the Standard Operating Procedure. From the above basic definition of SOP, SOP has the following intrinsic features:
SOP is a standard operating procedure. The so-called standard, here is the concept of optimization, that is, the operating program that is not written casually can be called SOP, but must be the optimized operating program design that can be realized under the current conditions through continuous practice. To put it more mundanely, the so-called standard is to refine, quantify and optimize the relevant operational steps as much as possible. The degree of refinement, quantification and optimization is understood by everyone under normal conditions without ambiguity.
SOP is not a single system. Although we can define each SOP separately, from the perspective of enterprise management, SOP cannot be a single one. It must be a whole and a system, and it is also indispensable for enterprises. Yu Shiwei also mentioned in his lecture: a company has two books, one is a Red Book, the company's strategy, that is, the operational guidance program; the other is the Blue Book, SOP, standard operating procedures, and This standard operating procedure must be refined and quantified.
Develop department, basis and role
The SOP is a standard workbook, which is a detailed standard work instruction for the various processes of the project, and is used by the manufacturing site operators. The production department operates in accordance with this SOP.
SIP is the inspection standard test, which is the standard inspection guide and standard made by the quality engineer for product feeding, process and finished product. Quality department personnel inspect the production in accordance with SIP.
SOP is for the manufacturing process of the product, it is to guide you how to make the product, it is based on the drawing and process requirements of the product, and SIP is the inspection process for the product. It is to guide you how to inspect the product. It is based on the product standard or Specifications. SIP is based on customer specifications and its own standards. SIP can be considered in the production process of SOP. For example, the verification operation in SIP can refer to the operation method in the SOP.
SOP IE staff production will reflect the working methods & standards, using materials, tools & equipment, standard working hours SIP QE staff production will reflect the inspection methods, tools & equipment, sampling standards, defect judgment definition
Production essentials
(1) The production method of SIP
Should SIP be marked with the key control size or the control of the key size according to the engineering drawings? If the key dimensions are marked, some products have a lot of key sizes, and some key sizes are not well described in words. How do we test them? Let's talk about the essentials of making SIP.
SIP is for QC (IQC and OQC), so SIP should be simple, easy to understand, and easy to operate. The following points should be noted for the dimensions:
1. When referring to the engineering development of this product, the key dimensions listed, SIP inspection size should not be too much;
2. The size involved in the assembly must be the key control (need to understand the process of product assembly)
3. The size specified by the client;
4. The drawings are attached to the SIP as much as possible for convenient measurement; 5. Detection equipment is used as often as possible to avoid using CMM;
6. Design the gage as much as possible for combined or complex measured dimensions. (2) SOP production essentials
How to make SOP (standard operation procedure), SOP is the most basic and most important responsibility, a complete and latest and most standard SOP can not only regulate the production process but also affect the operation of the entire company. Many senior managers sum up a company like this: “A company has two manuals. One is a red book (quality manual) and the other is a blue book (SOP). “The scope and importance of the SOP can be seen. 1. Preparation before production
(1) Study the data provided by the customer or RD, and summarize all the conditions and specifications to form a “work noteâ€.
(2) Perform structural analysis on the samples, distinguish each engineering segment (SMT, AI, processing, plug-in, repair, assembly) and check whether the BOM order is correct.
(3) Establish the processing methods and specifications of parts and components; the distinction between safety parts. (4) Develop the production process, and arrange the workstation and write a flow chart.
(5) Confirm whether the arrangement of the station is reasonable, whether there is a balance of working hours, whether there is repeated confirmation and prevention of adverse outflow. 2. Making SOP
The principle of making SOPs is clear, easy to understand, and clear, so that operators can easily read and understand the contents, sequence, and benchmarks of the work.
The SOP of the production line is divided into four engineering sections: processing, plug-in, repair, and assembly. SOP content:
(1). Model name: Mainly based on the model name specified by the company, such as: S3359; if the model name of the customer is also included, such as: MS-320. (emphasis)
a. It is not possible to indicate the model name in a series of models. Each model must have its own SOP and cannot be shared.
b. The model name specified by the company and the model name of the customer must be distinguished by color.
(2). Job Name: Indicates the job name for this workstation. Such as: dispensing, tin surface inspection „.
(3). Job segment: Indicates which project the job is located in. Such as: rotor segment, stator segment, assembly segment. . . . (4). Station: Mark this station in the first station of the project section to facilitate the cable. (5). Job Description: Indicates the work items and order of this workstation. (emphasis)
a. Indicate the job confirmation (priority job) for the previous workstation. b. Scheduling of the job sequence. c. For safety and safety parts, it must be marked.
(6). Note: Indicate the content and requirements of each work item. (emphasis)
a. The order number of the cautions must correspond to the job content.
b. Explain the requirements of the customer or the design of the relative operation, if not required to be in accordance with the general standard of PH. c. Regarding the direction indication, you need to use the relative position (such as “+ pole toward C10â€), and you cannot use the direction indication (such as “upâ€, “,†“frontâ€, “backâ€) to prevent the difference in recognition. d. If there are extensions, use similar parts and indicate the difference.
(7). Illustration: Describe the work content and precautions by drawing or taking pictures. (emphasis)
a. Use the color box to distinguish between inspection and confirmation; the operation of the station; and safety parts. b. Mark the order of the job.
c. The direction of the drawing on the icon, the object must be consistent with the actual operation.
d. For the work of the assembly (eg, heat sink processing, „..) use the explosion map as much as possible or use the continuity picture description.
e. The marking of the relevant baseline must be clear. (8). Use Tools: Indicates the tools, fixtures, instruments, and tools used to set up this workstation. (emphasis)
a. The setting conditions of the tool need to confirm whether there is a customer or design requirement. If not, set it according to the PH standard. b. Need to indicate the consumables used, such as tin wire, paint pen.
(9). Parts used: The parts used in this engineering station must be marked with the part number, specification, engineering position and dosage. (emphasis)
a. The parts should be arranged in the same order as the job.
b. If there are substitute materials, they must be placed together, but the “S†must be added before the item number to distinguish. (10). Change Note: Record the changes and causes of this job change (emphasis)
a. Indicate the date of the change and the name of the person who changed it. b. If there is an ECN, the ECN number must be indicated.
c. The cause of the change must be indicated (eg, job improvement, design changes, customer requirements, safety requirements). d. The changes should be marked with symbols in each field to facilitate comparison. (11). Version: A guide to control this work. (emphasis)
a. The version coding rules are marked with capitalized English words, such as: “Aâ€, “B†„. b. If 26 letters are used up, use two English words, such as “AAâ€, "AB" „. . (12). Judgment: Indicate the standard of the operation. (emphasis)
a. The order number of the judgment mark shall correspond to the work content.
b. The specification of the judgment is prioritized by the customer's regulations; the second is the design requirement; the second is the specification of the PH operation.
c. The definition of OK and NG must be clear.
(13). Standard Hours: Indicates the standard time for this workstation job. (emphasis)
a. The station should be marked with “standard working hours†and “balanced working hoursâ€.
3. Management of SOP
(1). After the SOP is completed, it must be confirmed by the quality assurance and confirmed by the biotechnology supervisor. (The signature part cannot be printed on a computer other than the producer).
(2). Each model SOP must have a version of the LIST to indicate the version of the latest SOP for each workstation at that time.
(3). There must be a change note for the model SOP, including all changes to the SOP for all SOPs of the model.
(4). Papers and quality assurance units that are required to use the "A3" specification for the SOP are required to use the "A4" specification paper and must be signed.
(5). All SOPs must be printed out and the electronic files must be backed up.
SOP is to convert the customer's data into the company's internal data, to guide the production staff, to make products that meet the customer's requirements, so that the company's cost can be better controlled.
