Competition in today's society is a competition of talent, management competition, and in the P CB enterprise management competition, the most valuable competition is the quality of competition and competition management, the face of fierce competition in the market, delivery Management has become a quality management after winning the market priority power of the powerful weapons, the following would like to talk about the issues we are most concerned about - PCB how to carry out delivery management.

1, PCB production type and problem

We all know that according to the type of production can be divided into two categories, one is the demand planning type (BT N): refers to the sales department according to product and market conditions and past sales performance, growth rate, market share, sales methods (BTO): refers to the need for sales forecast, after receiving the order of the customer to arrange the production of the product, the production of the product, the other is the order of production (BTO) A type, and PCB business is precisely the order type production enterprises, so how to arrange manpower, materials, equipment is the key to complete production.

Through a long time, we can see that the main factors that cause the production of chaos in the enterprise are:

(1) the sales department did not review the order, the order has a certain blindness;

(2) did not carry out the perfect capacity analysis;

(3) production plans and sales plans are not synchronized;

(4) material planning and production plan is not synchronized, and the quality of the requirements;

(5) key equipment poor maintenance, often faulty, repair is not timely;

(6) quality is not stable, the staff did not operate according to operational requirements, frequent rework, rework or scrapped the phenomenon;

(7) the daily production plan of each department is not synchronized with the weekly production plan, the production progress is not kept up;

(8) Engineering Department to deal with documents in a timely manner, resulting in an emergency too much or frequent changes in production plans, the actual production capacity of less than expected production capacity.

2, P CB production process

Then we look at the general P CB business production process:

Figure 1 production process

According to many years of personal experience and experience, in the above process on the delivery of the key role of several links is the order review, production planning, material procurement and manufacturing, and often these links did not cause enough attention.

Here on how to complete the above four links for a deeper discussion.

2 . 1 order review

P CB enterprises to receive customer orders after the information should be based on customer requirements for detailed entry, has been ERP management of enterprises directly into the computer, not yet computer management companies have to use the form for detailed registration, registration after the order review , Distinguish between general orders and special orders. We generally require the customer requirements or product requirements beyond the company's corporate standards when the order is summarized as a special order, in the TS16949 quality management system, the order review is a very important part, once listed as a special order to require sales, Production, quality, procurement, technology and other departments to conduct joint assessment to maximize the needs of customers to meet, and some special orders also require the production department to prepare quality plans, quality departments to track and monitor. But some small businesses often overlooked the management review of this one, all customers have orders we do, regardless of whether the conditions to meet the requirements, and ultimately the enterprise into a chaos. Delivery can not keep up, there are technical difficulties, lack of equipment capacity, testing technology, but the delay in the material and so on many factors restricting the development of the company, so a healthy and good business development must do a good job order review this ring.

2 . 2 production plan

"Do not plan, business still production" This is some of the lack of management of business leaders often say a word, in fact, do a good job in the production of P C B production is essential. As the production process is complicated and the delivery is short, the production cycle should be based on the weekly production plan and the daily production plan. A small number of long orders can also be planned. How can the production plan be made? important. In order to do the production plan, first of all, we have to introduce a concept - capacity, that is to say production capacity: This refers to the equipment in a certain period of time can produce the number of products, usually "capacity = time × production area" For the calculation method, to find the company's weakest production capacity and capacity of the largest link, so the production capacity can be divided into normal production capacity and maximum capacity. Normal production capacity refers to the annual production capacity of the average production capacity of equipment, and the maximum capacity is the production equipment can produce the maximum output or can arrange the maximum load.

(1) capacity analysis

Often the capacity analysis is mainly for the following aspects:

① the load capacity of the mechanical equipment used in manufacturing - the equipment load capacity;

② the total production of the product standard time and the standard time of each process - human load capacity;

③ preparation time of material preparation - pre-preparation capacity;

④ the size of the production site or the number of test tools one by one load capacity.

(2) capacity adjustment

So that once the emergence of short-term manpower, equipment overload, the adjustment method generally have the following:

① overtime, two shifts or three shifts to extend working hours;

② through training to improve staff proficiency or increase the temporary workers:

③ can be processed outside the processing of products processing:

④ there are difficulties and can not be scheduled delivery of the sales department should promptly communicate with customers, delay delivery.

We can through the following example to clarify the above problems, the following is a typical example of production enterprises,

Figure 2 a business manpower equipment index and capacity comparison table (two shifts)

It can be seen from Figure 2 that with the increase in human equipment index, monthly production capacity also increased, but not directly proportional. This means that only by looking for key departments and weak links as a breakthrough to find a solution is to improve production capacity is an important means, if necessary, the increase in manpower and equipment can achieve a multiplier effect, and if not necessary, it can not achieve the purpose of upgrading production capacity , On the contrary will result in a waste of manpower and equipment resources.

So we need to analyze the problem must be prioritized, do the urgent and important things, do not urgent and important things. Second is urgent and not important things, do not urgently do not matter on the last thing to do.

(3) other factors.

Know how to improve production capacity for the plan to provide a pre-guarantee, but because the order delivery time is short, time is urgent, do a good job in the production plan need to consider more factors, usually small and medium-sized P CB companies will be sales plans and production plans , And do the following aspects of the work:

① whether the full support of human power, can not, overtime, increase people will be able to be resolved;

② whether the equipment is intact, its production capacity can reach the scheduled capacity, if the manpower or equipment can not be achieved, whether the foreign partners are resolved;

③ whether the material in place, not in place how to solve;

④ whether there is a problem with the process, whether the problem can be resolved within the specified time;

⑤ The plan should also retain appropriate capacity to cope with emergencies or accidents.

(4) week plan and day plan.

Therefore, the only way to establish a complete weekly production plan and the daily production plan, is the basis of regular delivery, and it must have the following functions:

① to facilitate the grassroots production departments to master the daily production schedule and the completion of the situation;

② easy to grasp the various departments and the workload of each device, and make appropriate adjustments. But also in the production plan should also be prepared after the following aspects of the preparation to ensure the smooth completion of the plan.

A Personnel: Whether the process personnel meets the demand quantity;

B equipment: equipment is enough, whether there is an exception;

C film, drilling, milling machine files, mold, clamp fixture is prepared to fully, its quality is good;

D Material: whether the material in place within the specified time;

E production process: whether the production process and the manufacturing process in conflict;

F quality control: whether it is conventional quality control or has a special need to prepare quality plan;

G training: whether the staff is familiar with the operation of this post, how the speed, whether it will affect capacity. The only way to be considered a relatively complete production plan, then the company according to their own process with the above plan points to prepare a smooth, clear and reasonable production schedule.

2 . 3 material procurement

Material procurement is an important part of enterprise management, production can not be normal, material procurement is the key, only in the procurement of timely, qualified quality under the premise of qualified products to be produced. Some of the leadership of the business sector often despise the procurement or attention to the degree of procurement is not enough, which in many cases on the production caused by the phenomenon of downtime to be expected, and the material in place and began to tense goods, time is tight, the problem is more, quality also followed It is necessary to establish a corresponding list of qualified suppliers and develop corresponding procurement standards. Quality, not arranged for personal management, their own incidental piggyback, the lack of appropriate procurement plans, often appear to be expected to stop and the product does not meet the quality requirements of the phenomenon, in fact, is a greater waste. A complete set of procurement process should be: material control department or material warehouse procurement application a summary of the procurement of a demand for the preparation of a procurement plan once the arrival of a single arrival inspection a qualified stand. Failure to return only to ensure the completion of the procurement of materials in order to ensure the smooth completion of the production plan.

2 . 4 manufacturing process
The manufacturing process generally divides it into two processes: one is scheduling and the other is field management.

(1) Scheduling

As the workshop management or grassroots executives in the production plan issued according to the plan after the production schedule, the schedule should pay attention to the following points:

① According to the delivery period, the shorter delivery, the more urgent the time, the more time to arrange the production, and can use red on behalf of the urgent production, yellow on behalf of the special order flow table to distinguish priorities.

② According to the complexity of the process to consider the more the process, the more complex products, production time is longer, should be considered, it is best to track someone.

③ for the focus of the customer should also be based on the order of the assessment of the focus and general classification, usually the sales department will be based on the importance of customers to customers into A, B, C three categories, A class of customers should be the highest priority treatment, B Class times, C class even more times

④ According to the capacity of various departments to arrange staff, time, can not appear production bottlenecks or downtime to be expected.

(2) site management

Site management refers to the departments according to the production line on the human, equipment, materials, workers and other aspects of labor proficiency to arrange production, but also pay attention to the following aspects:

① staff division of the requirements of a reasonable, the better the technology, the faster the staff to arrange more difficult, more tight, the number of more products.

② staff on the daily maintenance and maintenance of equipment to develop good habits, regular inspection and maintenance, maintenance of equipment often in the most critical time problems, the entire production plan will have a great impact, so also To arrange for management and maintenance.

③ product delivery successively, the requirements in the field production at a glance, training every employee has a sense of delivery, for the most practical small and medium enterprises is in each production process suspension production schedule card.

④ each department daily production report will be submitted to the production department, to facilitate the production department summary of the production plan to achieve the situation, if necessary, the appropriate plan to adjust.

In short, on how to complete the delivery is a system of enterprise engineering, not simply solve a number of specific problems can solve the fundamental problem, the need for long-term practice and on-site management experience to be flexible use, so as to reach Period and quality of the perfect unity.
