Abstract
The utility model discloses a tin-spraying matched device of a printed circuit board (PCB), which comprises a preprocessing device, a tin-spraying machine, a cooling box, a postprocessing device and a preheating box, wherein the preprocessing device, the tin-spraying machine, the cooling box and the postprocessing device are sequentially connected, and the preheating box is arranged between the preprocessing device and the tin-spraying machine. The preheating box is added so that buffer preheating time is prolonged, board explosion caused by inconsistent contraction coefficients of boards and copper skins in sudden high temperature is avoided, production quality is improved, and production cost is relatively reduced.
Description
Technical field
The utility model relates to a kind of spray tin corollary apparatus, is specifically related to a kind of PCB spray tin corollary apparatus.
Background technology
In the PCB production process, spray tin is need plate be put into the tin-spraying machine high-temperature process in the process of surface treatment, particularly some thick copper coins and high TG sheet material; Need pretreating device that the spot of plate is cleaned before the spray tin, meet water and just cool down through little erosion, the washing back sheet material of pre-treatment, though through oven dry; But plank enter the tin stokehold maybe needs etc. tin to be painted, the temperature of words plate thus reduces, at present; When spray tin operation, a lot of processing enterprises directly put into the tin stove with product to spray tin, and the temperature of spray tin is higher; Behind spray tin, can occur to have a strong impact on the quality of product, cause scrappage high owing to sheet material and the inconsistent plate bursting phenomenon that causes of copper sheet constriction coefficient; Production cost is high; The method that can effectively solve this phenomenon is to purchase automated production equipment, but the cost of investment of automation equipment is higher relatively, also is a kind of burden concerning a lot of small business.
The utility model content
The purpose of the utility model is to provide a kind of available buffer heating time, thereby avoids sheet material and the inconsistent PCB spray tin corollary apparatus that causes the plate bursting phenomenon of copper sheet constriction coefficient.
For realizing this purpose, the utility model has adopted following technical scheme:
A kind of PCB spray tin corollary apparatus comprises the pretreating device, tin-spraying machine, cooler bin and the after-treatment device that connect successively, and PCB spray tin corollary apparatus also comprises preheating cabinet, and said preheating cabinet is located between pretreating device and the tin-spraying machine.
In process of production, pcb board is through pretreating device, and temperature reduces relatively; Directly pcb board is put into tin-spraying machine and spray tin, from low temperature to high temperature, the temperature difference of plate is very big; Increase preheating cabinet; Can play the effect of transition heating to the temperature of plate, effectively alleviate high-temperature time, avoid sheet material and the inconsistent plate bursting phenomenon that causes of copper sheet constriction coefficient in high temperature suddenly.
The utility model contrast prior art has following advantage: increase preheating cabinet and prolonged buffering warm-up time; Avoided sheet material and the inconsistent plate bursting phenomenon that causes of copper sheet constriction coefficient in high temperature suddenly; Improve the quality of producing, lowered production cost comparatively speaking.
Description of drawings
Accompanying drawing 1 is the flowage structure figure of the utility model.
Embodiment
Existing with reference to accompanying drawing, further explain the utility model.
As shown in Figure 1, a kind of PCB spray tin corollary apparatus comprises the pretreating device 1, tin-spraying machine 3, cooler bin 4 and the after-treatment device 5 that connect successively, and PCB spray tin corollary apparatus also comprises preheating cabinet 2, and preheating cabinet 2 is located between pretreating device 1 and the tin-spraying machine 3.
Do not have surface treated sheet material to be easy to generate phenomenons such as oxidation, carrying back and forth also can make has greasy dirt on the plate, destroys the quality of product; Therefore, pcb board need pass through little erosion, washing and the oven dry of pretreating device 1, and the temperature of oven dry cooling back sheet material reduces relatively; Directly pcb board is put into tin-spraying machine 3 and spray tin, from low temperature to high temperature, the temperature difference of plate is very big; Increase preheating cabinet 2, the time of baking is 150 ℃/45min, can play the effect of transition heating like this to the temperature of plate; Effectively alleviate the heat time, avoided sheet material and the inconsistent plate bursting phenomenon that causes of copper sheet constriction coefficient in high temperature suddenly, pcb board sprays tin from tin-spraying machine 3 after; Get in the cooler bin 4 and cool off, simultaneously, in after-treatment device 5, carry out subsequent treatment.
Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection range of the utility model.
Claims (1)
1. a PCB spray tin corollary apparatus comprises the pretreating device, tin-spraying machine, cooler bin and the after-treatment device that connect successively, it is characterized in that, PCB spray tin corollary apparatus also comprises preheating cabinet, and said preheating cabinet is located between pretreating device and the tin-spraying machine.
